Which sofa is better: spring or polyurethane foam. Spring block and polyurethane foam. Which filler for upholstered furniture should I choose? What is better: foam rubber or polyurethane foam?

Sofas are indispensable interior items in any home or apartment. Most often they are installed in the living room. When choosing important has a spring block for the sofa, which is of high quality and comfortable to use. They are presented on the market in different types, so when choosing a specific piece of furniture, you certainly take into account what kind of spring block it contains. The ease of use of the product for its intended purpose, as well as the possibility of using it as the main place to sleep, depends on this.

Advantages and disadvantages

As a rule, these systems are equipped with sofas that are folding, so after transformation a comfortable and fairly large sleeping place is formed.

The advantages of using such furniture include:

  • when choosing quality product its long service life is guaranteed, so it will be possible to use it as the main place to sleep for many years;
  • the springs easily support a person’s weight, so even overweight people will sleep comfortably on the products without experiencing discomfort;
  • spring sofas are formed in such a way as to take into account the structural features of the human body, so in any case comfortable conditions are created for constant and comfortable sleep;
  • high-quality springs are resistant to deformation, therefore, even after a long period of use for their intended purpose, they do not lose their parameters and properties;
  • High-quality and environmentally friendly components are used in the creation process, so it turns out good mechanism, which is pleasant to use;
  • different types of sofas are equipped with a system, which include book sofas or products equipped with other transformation mechanisms;
  • Many manufacturers offer different types of mechanisms with blocks at reasonable prices, so these designs are considered affordable for every buyer.

Types of spring blocks

However, these types of sofas are not without some disadvantages. For example, they often use inexpensive foam rubber as padding, and this material, after a short period of use, loses its elasticity and shape, so it becomes simply impossible to sleep or even sit on such a product. Also, inexpensive systems have low damping characteristics, so the springs often sag.

Types of springs

There are several types of elements installed in upholstered furniture. They differ in their formation features and properties, as well as cost and parameters. When choosing a certain option The characteristics of each model should be taken into account.

Spring-based blocks can be:

  • dependent, also called bonnel, and they are usually found in older models of sofas, and also have affordable price. Here all the springs are connected to each other using strong metal wire. Therefore, if a significant impact is exerted on one spring, then the neighboring elements are pressed through;
  • independent, with a high orthopedic effect, therefore truly optimal and safe conditions for the spine of a person who constantly uses this sofa to sleep. Each spring in such a block is located in a separate case, and all elements are connected into special tapes that are glued together. If you press on one spring, it will not affect the neighboring elements in any way. Due to this it is guaranteed optimal maintenance problem areas the human body, and especially the lower back.

Dependent springs
Independent springs

Each species has its own subspecies that have certain characteristics. It’s quite difficult to say which is better to choose. Each buyer independently decides which type is most optimal and suitable for him. A sofa book with this type of mechanism is produced, and designs with other transformation mechanisms are also presented on the market.

Independent

An accordion sofa with independent spring elements is often found, and they are also built into other varieties of this piece of furniture. This is due to the fact that independent springs have certain advantages:

  • all the springs are in a separate case, so a high-quality orthopedic effect is ensured, and using this sofa is actually very pleasant and simple, since there is no pushing effect;
  • lying on such a sofa, the body does not spontaneously shift to the middle of the sleeping place;
  • a book sofa with a spring block, which has independent springs, will never creak, even after a long period of use;
  • Various fillers are placed on top, for example, foam rubber or felt, coconut coir or polyurethane foam, as well as other materials.

Internal structure of the mattress

If a spring system with independent elements is better for the buyer, then it is advisable in the selection process to focus on models with a large number of these elements, which will ensure the formation of a high-quality and comfortable sleeping place.

A sofa with an independent spring block can be used even by two people, and they will not roll towards each other. This option is considered optimal for purchase. Independent springs for sofas are used for various transformation mechanisms. IN different blocks The number of springs used may differ, and inexpensive products are those in which this number is 250, and more expensive models are equipped with 1 thousand springs or more.

Bonnell

These blocks belong to the economy class, therefore they are considered the most popular and frequently encountered. Their main features include:

  • they are durable, convenient and comfortable;
  • are formed using special spring cups with two cones, and high-carbon steel is used to create them, which is durable, reliable and environmentally friendly;
  • the springs are laid on a special base, and it is formed from various materials, for example, plywood or MFD;
  • if the bonnel is used for corner models of sofas, then additionally along the edges it is lined with special boxes formed from polyurethane foam;
  • On top of such a structure a foam layer or a layer of felt and batting is created.

Springs for bonnel spring block

These blocks can be embedded for different mechanisms transformations, which is why they are found in accordions or Eurobooks. The service life predicted by manufacturers is 10 years, but if a truly high-quality design is chosen, then it can be in operation for many more years, delighting owners with high quality.

But such structures have poor orthopedic properties, and therefore are considered not very pleasant, useful and comfortable for constant use as a place to sleep. However, their price is considered acceptable for every buyer.

Bonnell spring block device

This spring system assumes that initially textile pockets are formed, separated from each other. They are then connected to each other in the middle. The result is a block with for a long time service, since the springs are not connected to each other. Even if, under certain circumstances, the integrity of one or more elements is compromised, this will not affect the quality of the entire sofa.

Which block is optimal? If you choose this system, then the number of springs should not be less than 435 pieces, since otherwise it will not be able to cope with high loads, and also will not be able to serve for a long time.

Book sofas equipped with this block are comfortable. This is due to the supporting effect as the body weight is distributed across multiple supports. It is easy to relax and have a good rest on such a piece of furniture. However, the cost of this system is at high level.

Spring block multi-package

Snake

This block is considered the simplest and most traditional. Here, all the springs are fixed on a special frame, for which special reliable fastenings are used. As a result, the seat receives a special springing effect. Foam rubber or felt is laid on top.

This block can be used for a seat or a backrest. The disadvantages are that the block is quite soft and unstable under various loads, so after a short period of operation it begins to sag. Therefore, it is recommended to use sofas with this design quite rarely, since they are considered unsuitable for constant use for sleeping.

Selection rules

It is difficult to say which specific spring block is of the highest quality, optimal and suitable, since each future user must focus on his own preferences, capabilities and desires. However, some expert advice stands out to help you make the right choice:

  • it is initially decided for what purpose the spring piece of furniture will be used, since it can be used as a bed every day or several times a year;
  • the optimal transformation mechanism is selected, which is convenient and reliable;
  • the type of spring block is determined, and it is important to focus on your own preferences and the state of the body, as well as the weight of the planned user;
  • additional layers in the block are selected, and the quality of the entire structure depends on them, since foam rubber products quickly fail, and coconut coir is characterized by increased rigidity, so the best option for the future owner is selected;

In short, polyurethane foam in a sofa is a filler hidden under the upholstery of the sofa. It is also furniture foam, it is also polyurethane foam. It is used as a filler to give the divag softness and elasticity due to its highly elastic properties. A sofa with high-quality PPU filling will not fall through and will not be hard.

Types of polyurethane foam

The PPU filling is based on block foam rubber - in our case it is cut and twisted as required. Depending on the quality of the PU foam filler, there are several varieties; we will highlight the most popular:

    block or sheet polyurethane foam. The advantage of such a PPU filler is that during its production it can be made either softer or harder.

    molded or cast polyurethane foam. Such fillers are created in blocks. The sofa may include many of these molded PPU blocks. The plus is that the backs and seats are soft and comfortable.

    highly elastic polyurethane foam (HR). This is PPU High Quality. On a sofa with such filling you will not feel any pressing effect or excessive rigidity. The person's weight is distributed evenly across the sofa.

    viscoelastic polyurethane foam (VE). Aka MemoryForm, aka Memorix, aka “memoriform”. When planted, such a polyurethane foam material accurately reproduces the shape of the body, adapts to it and quickly returns to its original shape after the load is removed. One of the most expensive PPU materials. How to check that you have viscoelastic polyurethane foam? Just apply pressure with your palm and release - the dent should gradually disappear.

In the production of sofas, we usually use highly elastic polyurethane foam. For example, in the Dallas modular sofa, the soft seating elements are formed from two layers highly elastic polyurethane foam. They ensure optimal softness of the sofa seat.

PU foam filler in a sofa: pros and cons

    debris does not accumulate in the filler, it allows air to pass through

    elasticity

    if the filling is initially of poor quality, the sofa will sag over time

    rigidity with a spring block

Service life of PPU filler

A good PU foam filler will last 8 years on average; it’s easier - around 5 years. When compared with other fillings, the situation is as follows: sofas with regular foam rubber will last 3-5 years, with holofiber from 5 to 10 years.

Springs or PPU (polyurethane foam) are used at the base of upholstered furniture. And to choose a really good sofa you need to know the features of both fillings.

Our blog has. You can read more about its properties there. Today, let's look at the advantages of spring bases. And at the end we will give some advice on what to consider when choosing. After reading these two articles and our recommendations, you can easily figure out which sofa is better: spring or polyurethane foam.

There are three main types, which are made from steel wire.

Bonnel

A system of dependent springs interconnected. Under pressure, the bodies compress all at once, one pulling the other along with it. The oldest and cheapest manufacturing technology. In the 21st century, manufacturers have significantly improved consumer qualities this block.

  • Pros: inexpensive, practical, and most importantly, a time-tested option.
  • One of the disadvantages is the lack of proper body support. But this disadvantage can be compensated top layer made of highly elastic polyurethane foam.
  • Independent springs (TFK, Pocket Spring)

    Each spring is enclosed in a separate case and compresses independently of each other. This block has pronounced orthopedic properties and perfectly reduces the load on the spine.

    It is worth noting:

    A similar sofa costs significantly more than its counterpart with Bonnell. But can high cost be considered a disadvantage? We think not, if we're talking about about health. Everyone knows the obvious benefits of anatomical support for the body.
    • Maximum permissible weight - 120 kg
    • Advantages: high orthopedic index, comfort, durability.

    Snake block

    The springs have transverse bends and are made of galvanized steel. Outwardly they look like a crawling snake, hence the name. Ensures smooth seating and quiet operation. Long-lived among spring systems: service life is calculated in decades.

  • Advantage: they do not deform or stretch over time, they are the most durable.
  • Disadvantage: poor cushioning of the base, not recommended for use as a permanent sleeping place.
  • What should you pay attention to?

    When choosing any spring sofa pay attention to permissible load. The higher this number, the thicker the wire and the more springs on square meter. This means the furniture will last longer.

    If you choose a sofa with a Bonnell block, be sure to check the quality of the top soft layer. It is better to choose highly elastic polyurethane foam with a density of at least 30 kg/cub.m. If you are slim and weigh little, then you can easily sleep on such a sofa all the time.

    A sofa with an independent spring block is suitable for a child. Orthopedic doctors advise providing a child's bed with anatomically correct support to prevent spinal curvature.

    Furniture polyurethane foam - PPU


    Polyurethane foam (furniture foam, abbreviated as PPU) is one of the most common flooring materials for the production of upholstered furniture and mattresses. is a foamed, sponge-like material obtained by mixing several synthetic polymers. A feature of modern polyurethane foams is their exceptionally high physical and mechanical properties, which in some respects are superior to all types of rubbers. Today's market offers a very wide range of different brands foam rubber: standard, increased rigidity and hard, soft and super soft, highly elastic. Each type foam rubber distinguished by its quality characteristics and has its purpose in the manufacture of upholstered furniture.

    Polyurethane foam (PPU)- high-volume material with a porous structure. It is used in various fields- as a basis for seats in theater seats and driver's seats. Polyurethane foams are also used as filler for the production of upholstered furniture, as well as in spring mattresses, and independently in springless mattresses. Seats sofas and armchairs from furniture foam rubber quite elastic, easily restores its original shape. It is comfortable to sit on such a sofa, it adapts to the shape of the body, and is easy to get up from. Thanks to its qualities polyurethane foam is one of the most popular fillers for upholstered furniture.


    Foam rubber
    , purchased for our products furniture factory Alina, produced on Norwegian (LAADER BERG AS) and German (FECKEN-KIRFEL and ALBRECHT BAUMER) equipment. Quality of produced foam rubber achieved through automation production process and high-precision dosing of components. Strict adherence to production technology and a quality control system, as well as highly qualified personnel and high-quality raw materials from leading manufacturers, allow us to achieve the maximum positive characteristics foam rubber, which makes it competitive.

    Upholstered furniture filler - PPU (furniture foam rubber)- not only has low cost, but also unique properties, which in turn determine its popularity:
    * possibility of transformation, different rigidity, reliability, durability.

    Besides, for furniture foam rubber There are also many other important properties that need to be paid attention to. They are mainly associated with direct effects on humans. PPU (furniture foam rubber):
    * does not contain substances that cause allergies, does not accumulate or emit dust, does not mold, and is safe for the health of people and animals.

    All polyurethane foam used meets international hygiene standards and is treated with antibacterial, antiviral and antifungal compounds.

    Equipment and industrial lines for the production of polyurethane foam - for familiarization to customers of furniture products (note!!! the Alina Furniture factory is not a manufacturer of polyurethane foam, but only uses it as an internal filler in the manufacture of upholstered furniture)

    In this way polyurethane foam- it's high-tech upholstered furniture filler, which is characterized by increased strength and durability. In its structure, polyurethane foam consists of microscopic thin-walled cells filled with air. The properties of elasticity and resilience are determined by the fact that the volume of air in the total volume of the material exceeds 98%. To produce foam rubber of any type, special polyols, melamine, and fire retardants are used in the formulation so that the physical and mechanical properties (density, rigidity, cell size, elasticity, tensile strength, air permeability, residual deformation, elongation) meet the requirements of the Consumer.

    Furniture filled with polyurethane foamfeatures increased strength and durability

    IN furniture production are used various brands foam rubber with high strength indicators. They are used as filling sofas, armchairs and other types upholstered furniture, which ensures increased comfort of the models.

    Each brand of polyurethane foam has its own purpose. As a rule, different brands of foam rubber are used in combination with each other. Some are for parts of furniture that do not bear the main load: the backs of sofas, armchairs, armrests. Others are for places of moderate loads during furniture operation. Still others are for use in conjunction with transformation mechanisms, etc.

    Furniture factory Alina uses predominantly dense, highly elastic varieties. All brands polyurethane foam, which we use are safe, do not cause allergies and do not generate dust. These foam rubbers have hygienic certificates from the Ministry of Health, which allow their use in the furniture industry.

    Foam rubber
    The brands used also have a high degree of “air permeability”. At correct use of these brands, this indicator indicates the possibility of a long service life, good ventilation of the products and the relative comfort and durability of the products. Quality indicators are consistently maintained under long-term cyclic loads, which contributes to a significant increase in the service life of furniture. They have good sound-absorbing and insulating properties.

    Furniture polyurethane foam is a hygienic material that, when proper care and will last a long time in use, so you don’t have to worry about the longevity of your upholstered furniture.

    Sintepon

    Sintepon(colloquially sintipon or sentipon, sintepon or cintepon). What it is? What is he like? Why is there so much talk about him? Is he good or bad? Is it harmful to health or not? Sintepon- is an environmentally friendly elastic material with a high degree of elasticity. Synthetic winterizer is used as a filler in the production of upholstered furniture - sofas, armchairs, poufs - to give seats and backs angular relief while maintaining acceptable softness and comfort. Synthetic winterizer cannot be oxidized by atmospheric oxygen for a long time. Sintepon is moisture resistant and does not absorb moisture into the fiber structure.

    Sintepon- This is a voluminous non-woven fabric made of polyester fiber. According to the method of joining the fibers, it can be thermally bonded or glued. Sintepon- elastic-elastic material, used as a filler in the furniture industry in the production of upholstered furniture, serves to give it relief and softness. Sintepon- flooring material made of solid acrylic fibers arranged in parallel strands. Usually a layer of padding polyester is used to cover furniture foam rubber - ppu.

    Sintepon is one of the most affordable fillers. Its development is not difficult and is a fast and low-cost process. Sintepon is a lightweight, elastic and voluminous non-woven material that is used for various purposes and is characterized by great functionality along with good thermal insulation properties. Sintepon also used as a filler in bedding, blankets, clothing, including children's overalls. Sintepon- one of many artificial materials that do not cause allergies to anyone. Therefore, it is also used in the children's industry as a filler for pillows and clothing.

    Sintepon is environmentally friendly, does not succumb to light-ozone aging for a long time, resists fungal contamination, does not absorb moisture, and is absolutely harmless. Recently, technological developments have led to the emergence of fundamentally new, high-quality synthetic holofiber products, which are in fact no longer padding polyester.

    Recently, technological developments have led to the emergence of fundamentally new high-quality synthetic products holofiber, which is actually no longer a padding polyester.

    Fillerfiber- These are siliconized polyester balls that replace natural fluff. - one of the most modern materials, used in the production of upholstered furniture. The microstructure of holofiber is a spatial spiral (as opposed to straight fiber, as in padding polyester), which allows it to perfectly retain its shape and easily restore it. It is more hygienic than natural and other synthetic fillers, moisture-resistant, comfortable and cozy. This is an environmentally friendly, non-allergenic and non-toxic product.

    Filler fiber is a siliconized fiber that is formed into balls using special equipment. Thanks to this, unlike synthetic fiber, which, being budget option, is tightly stuffed into the pillow and, after distribution, is a tightly stuffed object; a pillow made of fiber, which is stuffed loosely and allows the fiber to move inside the pillow, creates a unique shape suitable only for you.

    Holofiber- material for filling pillows in the form of cocoon balls made of synthetic spiral fibers treated with silicone. The balls are twisted fiber treated with silicone emulsion. The fibers, intertwined with each other, form a springy structure. This property allows the fiber to quickly restore its shape after being crushed and to have high resistance to maintaining its shape over time. The fiber structure is soft, breathable, has anti-allergenic properties, does not absorb foreign odors, does not form dust, and does not form lumps. This filler is not flammable (melts, but does not support combustion).

    Fiber fiber has unique qualities:

    Durable. Finished goods using holofiber they quickly restore their shape after compression and are especially soft.

    Ecologically pure high-tech down substitute fiber does not cause allergies, which is very important for health modern man. Unique filler quality: hypoallergenic. The most important property of fiber filler is its hygiene, the ability not to absorb odors and dust, and as a result the absence of allergic reactions upon contact.

    Orthopedic properties. A particularly valuable quality of fiber filler is manifested in the fact that products made from it take the shape of the body. Sophisticated fiber processing technology allows them to move independently of each other, so the durable, springy structure does not fall off after prolonged use.

    Antistatic properties. Special antistatic treatment of our products is absolutely harmless to health.

    Environmental Safety. The environmental friendliness and non-toxicity of fiber fiber has secured its reputation as the most popular filler.

    Cozy microclimate. Fiber fiber consists of many twisted fibers, leaving air space between them, which allows the filler to “breathe”.

    Durability. Fiber fiber will not lose volume during operation like cheaper synthetic fillers. A product with such a filler easily returns to its original shape, even after prolonged deformation.

    Fiber combines important consumer properties, such as:

    1. do not cause allergies - hypoallergenic
    2. antistatic
    3. special thermal insulation and breathability
    4. orthopedic, firm, elastic, light and voluminous
    5. environmental friendliness and durability
    6. is an excellent substitute natural fillers

    Products using holofiber provide maximum convenience and comfort during rest and sleep. Fiber It is not inferior to down in softness, elasticity and comfort, while being absolutely hypoallergenic.


    Name of the filler, the cheapest existing filler that is widely used in furniture production. Today it is best alternative natural fluff. This fiber is treated with a special silicone emulsion, which gives it qualities that allow it to be called an artificial down substitute. - this is artificial down - a hollow, highly crimped siliconized fiber, 100% polyester, a single component of which in space has the appearance of a spiral spring. The length of the coil is 57 mm. These individual components, intertwined with each other, form a strong springy fiber structure. This property allows synthetic fluff to quickly restore its shape after being crushed and to have high resistance to maintaining its shape over time. The elastic, compressible structure of synthetic down is soft, breathable, and does not create a “greenhouse effect” during prolonged use.


    Lightness, softness, elasticity, volume, warmth, environmental friendliness, hypoallergenicity, resistance to washing and dry cleaning. synthetic fluff. The hypoallergenic and environmentally friendly nature of synthetic down is explained by the absence of substances harmful to human health in its production. In addition, synthetic fluff does not absorb foreign odors. It is not afraid of water; if it gets wet, it still retains heat.

    Synthetic down does not roll or fall off, which cannot be said about natural down. used as filling for backrests, armrests and decorative pillows and other upholstered furniture products.

    A multi-layer, highly elastic, thermally bonded fabric with vertically directed fibers and an aerodynamic layout, which has low residual deformation. - white, soft, delicate polymer. It has oriented vertical fibers and therefore works like a spring block. This one is soft and lush filler in the manufacture of upholstered furniture it is used as a filler for seats, backs and armrests of sofas and armchairs. Upholstered furniture made using Durafil filler has the best consumer characteristics: the seats and backs of sofas have the ability to restore their shape after pressure or weight loading, while retaining this feature for a long time.
    does not cause allergies, does not absorb moisture and does not support combustion. The filler does not harbor colonies of dust mites, moths and mold fungi. Right choice types of flooring materials and their proper combination largely determine the quality and comfort of upholstered furniture. The following auxiliary flooring materials are used in production: batting, quilted padding, felt, spunbond and many others.



    (type of non-woven fabric) - non-woven fabric obtained by calendering (rolling through hot rollers) polypropylene fibers. IN spunbond seat and back cushions are wrapped and used as technical fabric. This makes it easy to put on fabric covers, as the fabric glides over the spunbond. During operation spunbond protects soft materials from abrasion and matting, and also allows you to straighten the folds of the cover. Nonwoven- non-woven fabric, used to add volume and strengthen the fabric, prevent fabric stretching, reduce wrinkles, do not change the properties of the fabric, retain the size and shape of the product during use. From spunbond The inner covers of back cushions and decorative pillows are sewn. Properties: hypoallergenic (used in the production of hygiene products), non-toxic, tear-resistant, breathable.


    Polystyrene balls


    Foamedpolystyrene - foam balls, a lightweight cellular material consisting of hydrogen and carbon atoms. They are very mobile and do not form friction with each other, which allows products with this filler to quickly take the desired shape. Is filler for chairs and poufs “Bean-Beg”.
    The cover is stuffed with many small polystyrene balls. The advantage of the model is its lightness, so if necessary, the chair can be easily moved from room to room. The weight of Bean Bags ranges from one to five kilograms, depending on the size. Made from durable, beautiful fabrics, Bean-run filled with extremely light polystyrene foam balls. The balls deform over time under the weight of a person - this is a natural process. At the bottom of each product there is a zipper so that the cover can be washed or added expanded polystyrene filler as it shrinks. The use of unique technology has made it possible to rid the products of the accumulation of static charge and rustling, so it is a pleasure to be in them! Bean Bag Filler must be treated with antistatic agents and components to reduce friction (15-20 times) - this distinguishing characteristic filling for poufs. The expanded polystyrene filler does not “creak” and does not accumulate static electricity!

    Vatniki- this is cotton wool, covered with fabric on one or both sides and stitched with threads. The following fabrics are used for the manufacture of quilted jackets: investment, sack, technical calico, gauze. Vatniki quilt with threads on sewing machine parallel rows with a certain distance between rows.

    Thus, quilted flooring - natural material , represents two layers thick fabric with a 5-centimeter layer of cotton wool laid between them. Vatnik- one of the fillers for upholstered furniture. Technologically flooring padded jacket the spring block is covered to give greater softness and evenness sleeping place sofas Vatnik It is widely used in the furniture industry as a cushioning material between other fillings of sofas, as well as to increase the comfort of a sleeping place.

    - dense non-woven textile material from felted wool. It is usually made in the form of panels that have different thicknesses, depending on the purpose.

    INoilok- one of the mandatory fillers for upholstered furniture, natural material, rolled through hot cylinders on both sides. A hard crust forms on the surface of the material, which makes the material very wear-resistant.

    Used in furniture factories in production upholstered furniture products - sofas and armchairs as a cushioning material that serves to neutralize the feeling of springs and protects polyurethane foam - PPU from contact directly with the spring block, prevents it from being pressed, and also improves the consumer properties of upholstered furniture.

    Rubber-fabric belts

    Most often in furniture upholstery a frame formed furniture tapes - belts. They are located in the inner part of the seat and back, and for greater strength they are woven together perpendicular to each other. The tapes, as a rule, are tightly stretched and should completely cover the space on which the springs or filler will be located during the production or upholstery process.

    Rubber-fabric belts consist of rubber and synthetic fibers, compressed and glued together. Rubber-fabric belts stretched in the form of a grid on a wooden frame - this is a type of base sofas and armchairs, chair backs. They are tensioned by a special machine that ensures uniform tension of the belts. have varying degrees of stretch. Softer belts are used on the backs of upholstered furniture, while harder ones are used on the seats of sofas and armchairs.

    Plates for transformation mechanisms

    are made on special equipment from beech or birch veneer. IN last years beech armor is rare. Perhaps the reason for this is that they are much more expensive than birch ones. Lata- This is a bent-glued product. Layers of wood special technology glued together, resulting in a bent product ( armor), which has the ability to bend under the load placed on it. On a metal frame armor are in special plastic lat holders, which are fastened with brackets over the frame. So armor They hold tighter and don't fall out. also installed as a base for the flooring of some models of upholstered furniture, as well as for metal frame mechanisms for transforming sofas and armchairs.

    Breakage or deformation (loss of bending) are the main defects of bent-glued elements. The batten breaks, as a rule, in the middle part due to loads exceeding the norm. Deformation refers to the process of natural wear and tear during operation. It must be said that the more armor is installed, the less each of them is deformed. The damaged armor bends in the opposite direction or becomes straight. The armor cannot be repaired, so if it breaks or becomes deformed, it must be replaced.

    "Snake"(snake spring block) - is a type of springs that are used in the furniture industry. “Snake” works in tension and in most cases they are used at the base of soft elements, such as furniture seating. The springs are attached to the frame of the sofa across.

    The number of springs placed in furniture depends on its size, as well as on its purpose. Spring snake Can be used in beds, couches, mattresses as well as sofa beds. Such springs can be attached different ways. The frame of the product, which has a base made of these springs, is stable and does not sway. The main advantages of using “Snake” springs are the level base of the sofa, as well as noiselessness.

    Springs for sofas and chairs made of galvanized metal and shaped like " snakes"When making seats, large cross-section wires are used, so they are stiffer than on the back. To prevent the seat from sagging, the spring is well hardened. Snake springs give upholstered furniture - sofa and armchair elasticity and orthopedic effect. They are installed on the frame as a base for soft elements, providing comfort and reliability in operation.

    Spring blocks

    Spring block- This is a block of interconnected springs. Each spring in the block works individually, which ensures orthopedic effect. Well known spring block widely used in manufacturing upholstered furniture. It is constantly modified, improving its qualities. Main function of the spring block- maintain the spine in the correct position. Design features help perform this function. Each spring adapts to specific area body without transmitting waves of movement. Uniqueness independent springs the fact that they relieve the spine as much as possible. Spring block ensures free air circulation and a healthy sleep climate. Factory Alina Furniture uses spring blocks “Pocket Springs” and “Bonnel”.

    Bonnell spring sofas

    The Bonnell continuous weave spring frame is one of the oldest spring frame designs. Sofas with double-cone spring block Bonnell Produced by all Russian and many Western companies. They belong to the most common group. It consists of 5 turns double-cone springs of high-quality steel wire (diameter 1.6, 1.8, 2.0 or 2.2 mm), interconnected by staples or wire, with special units to provide additional rigidity.

    Thanks to progressive elasticity, the spring at the beginning of the load is soft (compressible), and as the load increases, it becomes harder, which creates a relatively uniform distribution of body weight and its convenient location, and also makes it possible to avoid contact of coils, friction and creaking.

    The following materials are used as hard (to neutralize the feeling of springs and increase the rigidity of the mattress) and soft (for comfort, air and moisture exchange) fillers: spunbond, felt, polyurethane, batting, etc.

    Advantages:

    • Bonnel spring block l withstands heavy loads. For people weighing more than 110 kg, mattresses in this series are recommended.
    • Long service life (durability) - Bonnell spring block retains its elastic properties for a long time.
    • Because double cone spring block creates a large volume of air in the mattress, then such a mattress has good moisture exchange (an additional effect of bellows).

    All materials used for the production of sofas with Bonnell spring blocks undergo a series of tests and consist of high-tech compounds of natural fibers. All products are certified in accordance with hygiene standards.

    The world's most advanced technologies for working with spring blocks are used in the manufacture of products. Upholstered furniture has unique properties: environmental friendliness, elasticity, durability, ergonomics, aesthetics, and an unsurpassed feeling of comfort.

    The filling of upholstered furniture products complies with international hygiene standards, is treated with antibacterial, antiviral and antifungal compounds, and is hypoallergenic.

    Nowadays, sofas with independent springs have become very popular.

    Coil springs are sewn into separate textile pockets. For pockets, materials are used that allow air and moisture to pass through. Separate pockets with springs are connected to each other. These connections must be flexible so that each specific spring can exhibit its elastic properties.

    It is believed that the more springs, the better the anatomical properties of the mattress - this is partly not true. Optimal quantity springs (up to 350 per sq.m.). If there are more springs, then they become too narrow at the same height. Under load, the deformation of the springs occurs not in one plane (up and down), but in two or more planes (they bend on the sides) and entail other springs, which negatively affects the anatomical properties of the mattress and its quality.

    The frame with barrel springs in the pockets, unlike the Bonnell spring frame, has the properties point elasticity and thus very easily takes the shape of the body, i.e. mattresses with such a frame are orthopedic.
    However, despite good flexibility, mattresses with pocket spring frames should not be used for automatically adjustable bed frames.

    The anatomical properties of a mattress are determined by its ability to distribute the load of the body as evenly as possible during sleep, taking its shape.


    Basic materials:

    • Spring wound from special grade steel spring wire, current-hardened high voltage. For each block spring there is a piece of wire with a length of 110 cm. To make 1 m2 of spring block, 282 m of wire is used.
    • Case from nonwoven fabric. It is durable, tear-resistant, and has excellent throughput and filtering capacity. Each spring of the block in a compressed state is located in a separate cover-pocket, thereby ensuring the necessary reserve of elasticity, maintaining the properties and durability of the spring block.

    Purpose:

    • Independent spring block used for production orthopedic mattresses. Functional purpose block - maintain the spine in the correct position. This task is accomplished through his design features. Each spring adapts to a specific area of ​​the body without transmitting waves of movement: that is, if a load is applied to one specific spring, neighboring springs are not compressed. But first of all, independent springs are unique in that they relieve the spine as much as possible.
    • Independent spring block serves as a support for all components of the mattress. Its surface is ideal for the adhesion of fillers (for example, latex fabric). In addition, such a unit ensures free air circulation and ensures a healthy sleep climate.
      The durability of the mattress depends on the quality of the block.
    • Independent springs They come in different heights and diameters, which provides spring blocks with different properties. Thanks to increased comfort and the possibility of multi-purpose use, blocks of independent springs are the product of the future.
    Equipment and industrial lines for the production of springs - to familiarize customers with furniture products (note!!! the Alina Mebel factory is not a manufacturer of springs, but only uses them as an internal filler in the manufacture of upholstered furniture)


    Independent spring block
    has special ergonomic and mechanical properties. It consists of cylindrical or barrel-shaped springs, each of which is in a closed bag and has no metal connection with the others. The compression of each individual spring in the block occurs independently of neighboring springs, so the mattress adapts to the shape of your body. The advantages of a mattress with independent springs are obvious. The springs are not attached to each other, so there is no “wave” effect.

    A sofa with comfortable filling will not cure back problems, but it will help relieve tension and fatigue in the muscles and relieve stress on the spine. The most pronounced orthopedic effect is achieved by sofas with a block of independent springs, which follow the contours of the body and allow the muscles to completely relax due to the uniform distribution of the load. Independent spring block standard configuration consists of insulated cylindrical springs that do not have a rigid metal connection between themselves. Due to this, the mattress itself “adjusts” to the shape of your body.

    The filling of manufactured upholstered furniture products complies with international hygiene standards. It is treated with antibacterial, antiviral and antifungal composition, hypoallergenic

    When buying a sofa or armchair, you pay attention to their appearance and are not interested in the internal contents: — The internal filling of sofas and armchairs is not simple— Sofa fillers— The internal filling of sofas and armchairs can be varied— PPU— Spring blocks— Independent springs— Various mechanisms for transforming sofas- Mattress

    Furniture polyurethane foam - PPU

    Polyurethane foam (furniture foam, abbreviated as PPU) is one of the most common flooring materials for the production of upholstered furniture and mattresses. PPU is a foamed, sponge-like material obtained by mixing several synthetic polymers. A feature of modern polyurethane foams is their exceptionally high physical and mechanical properties, which in some respects are superior to all types of rubbers. Today's market offers a very wide range of different brands foam rubber: standard, increased rigidity and hard, soft and super soft, highly elastic. Each type foam rubber distinguished by its quality characteristics and has its purpose in the manufacture of sofas.

    Polyurethane foam (PPU)- high-volume material with a porous structure. It is used in a variety of applications - as a base for theater seats and driver's seats. Polyurethane foams are also used as filler for the production of upholstered furniture, as well as in spring mattresses, and independently in springless mattresses. Seats sofas and armchairs from furniture foam rubber quite elastic, easily restores its original shape. It is comfortable to sit on such a sofa, it adapts to the shape of the body, and is easy to get up from. Thanks to its qualities polyurethane foam is one of the most popular fillers for sofas.Molded polyurethane foam (PPU) is a modern high-tech environmentally pure material, different increased wear resistance and durability. Usage molded polyurethane foam allows you to achieve maximum comfort for the seats and backs of upholstered furniture - sofas and armchairs. Foam rubber, purchased for the manufacture of upholstered furniture , produced on Norwegian (LAADER BERG AS) and German (FECKEN-KIRFEL and ALBRECHT BAUMER) equipment. Quality of produced foam rubber is achieved through automation of the production process and high-precision dosing of components. Strict adherence to production technology and a quality control system, as well as highly qualified personnel and high-quality raw materials from leading manufacturers, allow us to achieve the most positive characteristics of foam rubber, which makes it competitive. Upholstered furniture filler - PPU (furniture foam rubber)- not only has low cost, but also unique properties, which in turn determine its popularity: 1. possibility of transformation, 2. different rigidity, 3. reliability, 4. durability. In addition, for furniture foam rubber There are also many other important properties that need to be paid attention to. They are mainly associated with direct effects on humans. PPU (furniture foam rubber):
    1. does not contain substances that cause allergies, 2. does not accumulate or emit dust, 3. does not mold, 4. is safe for the health of people and animals.
    All polyurethane foam used meets international hygiene standards and is treated with antibacterial, antiviral and antifungal compounds. Thus, polyurethane foam- it's high-tech sofa filler, which is characterized by increased strength and durability. In its structure, foam rubber consists of microscopic thin-walled cells filled with air. The properties of elasticity and resilience are determined by the fact that the volume of air in the total volume of the material exceeds 96%. To produce foam rubber of any type, special polyols, melamine, and fire retardants are used in the formulation so that the physical and mechanical properties (density, rigidity, cell size, elasticity, tensile strength, air permeability, residual deformation, elongation) meet the requirements of the Consumer. A sofa filled with polyurethane foam is characterized by increased strength and durability In furniture production, various brands of foam rubber are used that have high strength indicators. They are used as filling sofas, sofas, ottomans, armchairs and other types upholstered furniture, which ensures increased comfort of the models. Each brand of polyurethane foam has its own purpose. As a rule, different brands of foam rubber are used in combination with each other. Some are for parts of furniture that do not bear the main load: the backs of sofas, armchairs, armrests. Others are for places with moderate loads during furniture use. Still others are for use in conjunction with transformation mechanisms, etc. We use predominantly dense, highly elastic varieties PPU. All brands polyurethane foam safe, do not cause allergies and do not generate dust. These foam rubbers have hygienic certificates from the Ministry of Health, which allow their use in the furniture industry. Foam rubber The brands used also have a high degree of “air permeability”. If these brands are used correctly, this indicator indicates the possibility of a long service life. PPU, good ventilation of products and relative comfort and durability of products. Quality indicators are consistently maintained under long-term cyclic loads, which contributes to a significant increase in the service life of furniture. They have good sound-absorbing and insulating properties. Furniture polyurethane foam is a hygienic material that, with proper care and use, will last a long time, so you don’t have to worry about the longevity of your upholstered furniture.

    Sintepon

    Sintepon(colloquially sintipon or sentipon, sintepon or cintepon). What it is? What is he like? Why is there so much talk about him? Is he good or bad? Is it harmful to health or not? Sintepon— is an environmentally friendly elastic material for filling sofas, with a high degree of elasticity. Sintepon is used as a filler in the production of upholstered furniture - sofas, armchairs, poufs - to give seats and backs angular relief while maintaining acceptable softness and comfort. Synthetic winterizer cannot be oxidized by atmospheric oxygen for a long time. Sintepon is moisture resistant and does not absorb moisture into the fiber structure. Sintepon is a voluminous non-woven fabric made of polyester fiber. According to the method of joining the fibers, it can be thermally bonded or glued. Sintepon- elastic-elastic material, used as a filler in the furniture industry in the production of upholstered furniture, serves to give it relief and softness. Sintepon- flooring material made of solid acrylic fibers arranged in parallel strands. Usually a layer of padding polyester is used to cover furniture foam rubber - ppu. Sintepon is one of the most affordable fillers. Its development is not difficult and is a fast and low-cost process. Sintepon is a lightweight, elastic and voluminous non-woven material that is used for various purposes and is characterized by great functionality along with good thermal insulation properties. Sintepon also used as a filler in bedding, blankets, clothing, including children's overalls. Sintepon- one of the few artificial materials that do not cause allergies to anyone. Therefore, it is also used in the children's industry as a filler for pillows and clothing. Sintepon is environmentally friendly, does not succumb to light-ozone aging for a long time, resists fungal contamination, does not absorb moisture, and is absolutely harmless. Recently, technological developments have led to the emergence of fundamentally new, high-quality synthetic holofiber products, which are in fact no longer padding polyester.

    Holofiber

    Recently, technological developments have led to the emergence of fundamentally new high-quality synthetic products holofiber, which is actually no longer a padding polyester. Fiber filler- These are siliconized polyester balls that replace natural fluff. Holofiber- one of the most modern materials used in the production of sofas. The microstructure of holofiber is a spatial spiral (as opposed to straight fiber, as in padding polyester), which allows it to perfectly retain its shape and easily restore it. It is more hygienic than natural and other synthetic fillers, moisture-resistant, comfortable and cozy. This is an environmentally friendly, non-allergenic and non-toxic product. Filler fiber is a siliconized fiber that is formed into balls using special equipment. Thanks to this, in contrast to synthetic fiber, which, being a budget option, is tightly stuffed into the pillow and, after distribution, is a tightly stuffed object, a fiber pillow, which is stuffed loosely and allows the fiber to move inside the pillow, creates a unique shape that is suitable only for you. Holofiber- material for filling pillows in the form of cocoon balls made of synthetic spiral fibers treated with silicone. The balls are twisted fiber treated with silicone emulsion. The fibers, intertwined with each other, form a springy structure. This property allows the fiber to quickly restore its shape after being crushed and to have high resistance to maintaining its shape over time. The fiber structure is soft, breathable, has anti-allergenic properties, does not absorb foreign odors, does not form dust, and does not form lumps. This filler is not flammable (melts, but does not support combustion). Fiber fiber has unique qualities:Durable. Finished products using holofiber quickly restore their shape after compression and are especially soft. Ecologically pure The high-tech down substitute fiber does not cause allergies, which is very important for the health of modern people. Unique filler quality: hypoallergenic. The most important property of fiber filler is its hygiene, the ability not to absorb odors and dust, and as a result the absence of allergic reactions upon contact. Orthopedic properties. A particularly valuable quality of fiber filler is manifested in the fact that products made from it take the shape of the body. Sophisticated fiber processing technology allows them to move independently of each other, so the durable, springy structure does not fall off after prolonged use. Antistatic properties. Special antistatic treatment of our products is absolutely harmless to health. Environmental Safety. The environmental friendliness and non-toxicity of fiber fiber has secured its reputation as the most popular filler. Cozy microclimate. Fiber fiber consists of many twisted fibers, leaving air space between them, which allows the filler to “breathe”. Durability. Fiber fiber will not lose volume during operation like cheaper synthetic fillers. A product with such a filler easily returns to its original shape, even after prolonged deformation. Fiber combines important consumer properties, such as:
    1. do not cause allergies - hypoallergenic 2. antistatic 3. special thermal insulation and breathability 4. orthopedic, resilient, elastic, light and voluminous 5. environmentally friendly and durable 6. is an excellent substitute for natural fillers
    Products using holofiber provide maximum convenience and comfort during rest and sleep. Fiber It is not inferior to down in softness, elasticity and comfort, while being absolutely hypoallergenic.

    Sintepooh

    Sintepooh- the name of the filler, the cheapest of the existing fillers that are widely used in furniture production. Today this is the best alternative to natural down. This fiber is treated with a special silicone emulsion, which gives it qualities that allow it to be called an artificial down substitute. Sintepooh- this is artificial down - a hollow, highly crimped siliconized fiber, 100% polyester, a single component of which in space has the appearance of a spiral spring. The length of the coil is 57 mm. These individual components, intertwined with each other, form a strong springy fiber structure. This property allows synthetic fluff to quickly restore its shape after being crushed and to have high resistance to maintaining its shape over time. The elastic compressible structure of synthetic down is soft, breathable, which does not create a “greenhouse effect” during prolonged use. Lightness, softness, elasticity, volume, warmth, environmental friendliness, hypoallergenicity, resistance to washing and dry cleaning, these qualities have synthetic fluff. The hypoallergenic and environmentally friendly nature of synthetic down is explained by the absence of substances harmful to human health in its production. In addition, synthetic fluff does not absorb foreign odors. Sintepooh is not afraid of water; when wet, it still retains heat. Synthetic down does not roll or fall off, which cannot be said about natural down. Sintepooh used as filling for backrests, armrests and decorative pillows and other upholstered furniture products.

    Durafil

    Durafil— a multi-layer, highly elastic, thermally bonded fabric with vertically directed fibers and an aerodynamic layout, which has low residual deformation. Durafil- white, soft, delicate polymer. It has oriented vertical fibers and therefore works like a spring block. This one is soft and lush filler in the manufacture of upholstered furniture it is used as a filler for seats, backs and armrests of sofas and armchairs. Upholstered furniture made using Durafil filler has the best consumer characteristics: the seats and backs of sofas have the ability to restore their shape after pressure or weight loading, while retaining this feature for a long time. Durafil does not cause allergies, does not absorb moisture and does not support combustion. The filler does not harbor colonies of dust mites, moths and mold fungi. The correct choice of types of flooring materials and their competent combination largely determine the quality and comfort of upholstered furniture. The following auxiliary flooring materials are used in production: batting, quilted padding, felt, spunbond and many others.

    Spunbond

    Spunbond(type of non-woven fabric) - non-woven fabric obtained by calendering (rolling through hot rollers) polypropylene fibers. IN spunbond seat and back cushions are wrapped and used as technical fabric. This makes it easy to put on fabric covers, as the fabric glides over the spunbond. During operation spunbond protects soft materials from abrasion and matting, and also allows you to straighten the folds of the cover. Nonwoven— non-woven fabric, used to add volume and strengthen the fabric, prevents stretching of the fabric, reduces creasing, does not change the properties of the fabric, maintains the size and shape of the product during use. From spunbond The inner covers of back cushions and decorative pillows are sewn. Properties: hypoallergenic (used in the production of hygiene products), non-toxic, tear-resistant, breathable.

    Polystyrene balls

    Foamed polystyrenefoam balls, a lightweight cellular material consisting of hydrogen and carbon atoms. They are very mobile and do not form friction with each other, which allows products with this filler to quickly take the desired shape. Is filler for chairs and poufs “Bean-Beg”. The cover is stuffed with many small polystyrene balls. The advantage of the model is its lightness, so if necessary, the chair can be easily moved from room to room. The weight of Bean Bags ranges from one to five kilograms, depending on the size. Made from durable, beautiful fabrics, Bean-run filled with extremely light polystyrene foam balls. The balls deform over time under the weight of a person - this is a natural process. At the bottom of each product there is a zipper so that the cover can be washed or added expanded polystyrene filler as it shrinks. The use of unique technology has made it possible to rid the products of the accumulation of static charge and rustling, so it is a pleasure to be in them! Bean Bag Filler must be treated with antistatic agents and components to reduce friction (by 15-20 times) - this is a distinctive characteristic of the filling for poufs. The expanded polystyrene filler does not “creak” and does not accumulate static electricity!

    Padded quilted flooring

    Vatniki- This is cotton wool, covered with fabric on one or both sides and stitched with threads. The following fabrics are used for the manufacture of quilted jackets: investment, sack, technical calico, gauze. Vatniki quilted with threads on a sewing machine in parallel rows with a certain distance between the rows. Thus, quilted flooringnatural material, consists of two layers of dense fabric with a 5-centimeter layer of cotton wool sandwiched between them. Vatnik- one of the fillers for upholstered furniture. Technologically flooring padded jacket a spring block is covered to give greater softness and evenness to the sleeping area of ​​the sofas. Vatnik It is widely used in the furniture industry as a cushioning material between other fillings of sofas, as well as to increase the comfort of a sleeping place.

    Felt

    Felt- dense non-woven textile material made from felted wool. It is usually made in the form of panels that have different thicknesses, depending on the purpose. Felt- one of the mandatory fillers for upholstered furniture, natural material, rolled through hot cylinders on both sides. A hard crust forms on the surface of the material, which makes the material very wear-resistant. Felt used in furniture factories in production upholstered furniture products - sofas and armchairs as a cushioning material that serves to neutralize the feeling of springs and protects polyurethane foam - PPU from contact directly with the spring block, prevents it from being pressed, and also improves the consumer properties of upholstered furniture.

    Rubber-fabric belts

    Most often, furniture upholstery uses a frame formed furniture tapes - belts. They are located in the inner part of the seat and back, and for greater strength they are woven together perpendicular to each other. The tapes, as a rule, are tightly stretched and should completely cover the space on which the springs or filler will be located during the production or upholstery process. Rubber-fabric belts consist of rubber and synthetic fibers, compressed and glued together. Rubber-fabric belts stretched in the form of a grid on a wooden frame - this is a type of base sofas and armchairs, chair backs. They are tensioned by a special machine that ensures uniform tension of the belts. Belts have varying degrees of stretch. Softer belts are used on the backs of upholstered furniture, while harder ones are used on the seats of sofas and armchairs.

    Armor

    Armor are made on special equipment from beech or birch veneer. In recent years, beech armor has been rare. Perhaps the reason for this is that they are much more expensive than birch ones. Lata- This is a bent-glued product. Layers of wood are glued together using a special technology, resulting in a bent product ( armor), which has the ability to bend under the load placed on it. On a metal frame armor are in special plastic lat holders, which are fastened with brackets over the frame. So armor They hold tighter and don't fall out. Armor also installed as a base for the flooring of some models of upholstered furniture, as well as for metal-frame mechanisms for transforming sofas and armchairs. Breakage or deformation (loss of bending) are the main defects of bent-glued elements. The batten breaks, as a rule, in the middle part due to loads exceeding the norm. Deformation refers to the process of natural wear and tear during operation. It must be said that the more armor is installed, the less each of them is deformed. The damaged armor bends in the opposite direction or becomes straight. The armor cannot be repaired, so if it breaks or becomes deformed, it must be replaced.

    Snake springs

    "Snake"(snake spring block) - is a type of springs that are used in the furniture industry. “Snake” works in tension and in most cases they are used at the base of soft elements, such as furniture seating. The springs are attached to the frame of the sofa across. The number of springs placed in the furniture depends on its size, as well as on its purpose. Spring snake Can be used in beds, couches, mattresses as well as sofa beds. Such springs can be attached in different ways. The frame of the product, which has a base made of these springs, is stable and does not sway. The main advantages of using “Snake” springs are the level base of the sofa, as well as noiselessness. Springs for sofas and chairs made of galvanized metal and shaped like " snakes". When making seats, large-section wires are used, so they are more rigid than on the backrest. To prevent the seat from sagging, the spring is well hardened. Snake springs give upholstered furniture - sofa and armchair elasticity and orthopedic effect. They are installed on the frame as a base for soft elements, providing comfort and reliability in operation.

    Spring blocks

    Spring block- This is a block of interconnected springs. Each spring in the block works individually, which ensures orthopedic effect. Well known spring block widely used in manufacturing upholstered furniture. It is constantly modified, improving its qualities. Main function of the spring block- maintain the spine in the correct position. Design features help perform this function. Each spring adapts to a specific area of ​​the body without transmitting waves of movement. Uniqueness independent springs the fact that they relieve the spine as much as possible. Spring block ensures free air circulation and a healthy sleep climate. Bonnell spring sofas The Bonnell continuous weave spring frame is one of the oldest spring frame designs. Sofas with double-cone spring block Bonnell Produced by all Russian and many Western companies. They belong to the most common group. It consists of 5 turns double-cone springs of high-quality steel wire (diameter 1.6, 1.8, 2.0 or 2.2 mm), interconnected by staples or wire, with special units to provide additional rigidity. Bonnel spring blockl withstands heavy loads.For people weighing more than 110 kg, mattresses in this series are recommended. Thanks to progressive elasticity, the spring at the beginning of the load is soft (compressible), and as the load increases, it becomes harder, which creates a relatively uniform distribution of body weight and its convenient location, and also makes it possible to avoid contact of coils, friction and creaking. As hard ( To neutralize the feeling of springs and increase the rigidity of the mattress) and soft (for comfort, air and moisture exchange) fillers, materials are used: spunbond, felt, polyurethane, batting, etc. Advantages:
    • Long service life (durability) - Bonnell spring block retains its elastic properties for a long time.
    • Because double cone spring block creates a large volume of air in the mattress, then such a mattress has good moisture exchange (an additional effect of bellows).
    All materials used for the production of sofas with Bonnell spring blocks undergo a series of tests and consist of high-tech compounds of natural fibers. All products are certified in accordance with hygiene standards. The most advanced technologies in the world for working with spring blocks are used in the manufacture of products. Upholstered furniture has unique properties: environmental friendliness, elasticity, durability, ergonomics, aesthetics, and an unsurpassed feeling of comfort. The filling of upholstered furniture products complies with international hygiene standards, is treated with antibacterial, antiviral and antifungal compounds, and is hypoallergenic.Sofas with independent springsNowadays, sofas with independent springs have become very popular.
