Project development.

The external view (draft design) of body products (or a block of products) is drawn at a scale of 1:10 or 1: 5 in two or three projections, depending on the complexity of the product. The drawing should contain the fundamental architectural, artistic and design solutions that give general views on the finish, device and principle of operation of the product, its aesthetics and basic sizes. According to the preliminary design, the simplest working documentation is being developed in the future.

The simplest working documentation includes general arrangement drawings developed according to the draft design. Preliminary design for products of lumped furniture, you can not develop, but replace it with drawings general view.

The number of cuts in the general arrangement drawings should be sufficient to obtain a complete picture of the product design.

In the drawing, the circles drawn by solid thin lines show the extension elements that should be drawn on an enlarged scale. The number of outriggers depends on the complexity of the product and should in each case be sufficient to assemble the product. Outline drawings are developed for connections made with spikes, various metal or plastic fasteners, and for complex profiles that require additional graphic explanation.

After the development of drawings, a product specification is drawn up. The specification includes parts made from boards, plywood, metals, plastics, as well as fasteners (screws, nails) and accessories.

The main dimensions of furniture items are chosen in accordance with the dimensions of the human body (anthropometric data), as well as with the dimensions of the items for which the furniture is intended to be stored. Taking into account anthropometric data, most furniture sizes are standardized.

Some anthropometric data of the human figure at rest, in motion and in the process of using furniture.

The comfort of the support products is due to the size of the human body. In addition, they take into account the relationship of the sizes of various products, the correct choice of them individual parameters... So, the height of the chair seat from the floor depends on the height of the table: at a table height of 720-780 mm, a chair with a seat height of 420-480 mm is comfortable, the table height for typing work can be reduced to 680 mm.

The width of the seats in the widest part of the chairs is not less than 360 mm, the width of the working chairs is 400 mm. If chairs and work chairs are made with backs that have curvature, then the radius of curvature of the lumbar (no more than 320 mm high) backs is 220 mm, ordinary (more than 320 mm high) backs - 450 mm.

When buying new furniture, most pay attention exclusively to its appearance, imagining how it will fit into the interior. Some take into account the comfort of the seats and the serviceability of the transformation mechanism of the sofa, forgetting about the size upholstered furniture... However, it is on the dimensions that you should pay attention in the first place, because the product should be placed in the place intended for it in specific rooms, providing sufficient comfort for those sitting.

To correctly calculate the dimensions of specific upholstered furniture, some indicators are taken into account. For example, you need to maintain a certain distance between the seated, so that they feel comfortable. However, the abundance of models and various standards are often confused, so it is worthwhile to understand them in more detail.

Standardization and dimensions of the sofa

Most countries use standard sizes when creating upholstered furniture. Some people think that this is superfluous, because standardization stifles imagination. And if the buyer does not fit, you can simply not buy the product. But there is a reason why dimensions sofas should be the same and it has little to do with the decisions of states or factories. It's all about medicine. It is she who limits the production of products that can adversely affect health.

For comfortable rest it is necessary to choose the right sofa in size so that there is enough free space on it. Through anthropometric studies, scientists have determined the average statistical values, because all people have different weights, as well as other parameters, so it is quite difficult to adapt to everyone. The sofa size standard stipulates that people can take different positions while relaxing. But at the same time, he does not impose the dimensions of upholstered furniture, but only sets the framework.

For example, a standard sofa should be calculated at 50 centimeters per person, and this is only for seating. A full size sleeping place the sofa must be at least 70 cm.

Height standards are determined by the manufacturers themselves, so the sofa can rise even a meter above the ground. There are no separate criteria for the backrest, armrests and other elements.

What sizes are sofas by type?

Most choose upholstered furniture that can be turned into an extra bed, because you can not only sit on it, but also accommodate guests or sleep on your own. There are several types of sofa products and each has its own characteristics, which should be considered.

Corner sofa: standard sizes

Corner structures are usually quite large and take up an entire corner in a room, using a minimum of usable space. it great choice for small room and the fold-out version provides a comfortable sleep. Among its features are:

• The structure consists of three parts- pairs of straight elements and an angle. The longest part is usually 130–150 cm.
• The presence of structures without armrests, taking up less space.
• Different parameters of a berth, the width of which can be 140-200 cm.
• The standard does not indicate what the width of the sofa should be, but most often it is 70 or 90 cm.
• An important element is the linen drawer, in which you can hide bed linen or other accessories.

Features of a straight sofa

This variety is considered the most common and it is he who becomes the choice of most residential premises. It is often installed along the wall, but sometimes it is also used to divide a room into different zones. The depth and size of the sofa can be different, it all depends on the mechanisms that help them unfold. The seating comfort depends on the depth.

When purchasing a straight model, it is imperative to take into account its dimensions when it is unfolded. However, the folded state is no less important, because often such products are supplemented with wide armrests.

Separately, it is worth highlighting that the sizes of such upholstered furniture can be very diverse, because it consists of different elements... If you wish, you can always separate them by changing the order. The color, size, as well as the number of details depends on the buyer, so everyone can independently choose the size of the depth, width and length of the sofa, giving it the shape of an angle, semicircle or even a zigzag. The size of one module is usually 60–100 cm.

How does footprint affect?

When choosing, they always take into account the approximate number of people who can use the sofa:

• A small 120 cm sofa is enough for one person to sit or sleep.
• The dimensions of the two-seater sofa are slightly larger, especially if it is married couple... For a comfortable rest or constant sleep, you need to choose a product with a length of at least 170 cm, but it is better if the length of the sofa is 190-200 cm, then it will be comfortable to sleep on it when unfolded. It is permissible to have a slightly smaller two-seater sofa, the size of the furniture will increase when unfolded and even with a length of 180 cm it will be comfortable to sleep.
• The most popular choice is the triple, and even couples choose it, just for more comfort. it optimal choice for those who like to gather in companies. The dimensions of a three-seater sofa are usually limited to 2 meters in length and 80 cm in width, although there may be more.
• There are four-, five or even seven-seater options. Their height and width differ little from standard models, and their width seat varies between 70-80 cm. They resemble a three-seater sofa, the dimensions of which have not changed, except for the length.

Height and other dimensions

Not too much attention is usually paid to the height of sofas, which is rather strange, because the back is very important element that supports the spine. Mostly the size of the back of the sofa depends on where it is used. Children's models are usually short, there are even products below 60 cm. Among the "adult" sofas, the modular versions are the smallest, with the height of their backs being about 70 cm.

Some models simply sit on the ground, while others have feet. The standard does not define the height of the sofa and it only depends on design idea... As for the armrests, their size, like the dimensions of the furniture itself, depends on the design. For example, a product in a minimalist style may not have armrests at all and be very comfortable, while a sofa for a baroque interior will take up a lot of space and provide for wide armrests.

Choice comfortable sofa- this is the main item of furnishing the living room. The comfort of spending time in the room depends on it. Often, when choosing upholstered furniture, we pay attention only to the main dimensions of products - length and width. The ability to install products in a room with specific planning and quadrature features depends on these parameters. However, a comfortable sofa should not only fit harmoniously in size and shape, but also have the correct height. It affects the fit and aesthetic perception of the product in the interior. But first things first.

Optimal height of a comfortable sofa

The optimal sofa height for an adult is 90-100 cm. The height of the seat itself should be at least 35-40 cm. Such parameters allow you to relax your muscles as much as possible.

Elderly people, as a rule, with back and joint problems, will do the taller and toughest option. It is easier to sit on it and get off it. Accordingly, it is recommended for children to choose sofas of lower height so that the child can easily sit on it without the help of an adult.

In assessing the comfort of the sofa, armrests and headrests are not the last place. The most functional can be called recliner models, in which each structural element can be adjusted in terms of inclination and height, which means that each person will be able to sit comfortably.

What determines the height of the sofa?

The height of the sofa is indicated in the product passport for the third in a row after the length and width. In this case, it is worth distinguishing between the total height of the product and the individual heights of its back and seat. Standard height seats - 42 cm, the back is calculated accordingly by the difference.

Conventionally total height standard sofa is 90 cm.However, it may vary depending on:

• From the type of sofa: straight, corner, bay window, modular.
• From the transformation mechanism: roll-out, unfolding, unfolding.
• On the features of a specific design.

Sofa type

Sofas that are placed in the corner of the room may well have a height of 100-110 cm. However, if the room is small, it is better to give preference to the standard parameter - 90cm. Products installed in the center of the room or parallel to the window, with a special high back are not perceived. Therefore, a suitable total height for such products is 70 cm, and the seating remains unchanged - 35-40 cm.

The height of modular sofas, which are quickly transformed, often does not exceed 70 cm. This parameter makes it possible to install the sofa anywhere in the room.

Transformation mechanism

The standard height of 90 cm is most often the sofas with transformation mechanisms, a book, a eurobook and a click-gag. This is due to the peculiarities of the elements that make up the berth - there the back becomes one of the main parts.

For unfolding mechanisms (English and French folding bed, sedaflex) is characterized by a height of around 100 cm, since inside the seat it is necessary to accommodate a berth in two or three folds, and the backrest automatically becomes higher.

Most roll-out models (dolphin, accordion and others) have removable cushions on the seat, which create a comfortable fit, but the back may not be too high.

When choosing a sofa bed with a transformation mechanism, it is necessary to take into account not only the height of the assembled seat, but also the actual height of the berth. Among the standard options:

• 20-40 cm - low berth;
• 35-45 cm - standard berth;
• Over 45 cm - high berth.

Design features

The height of the sofa is also influenced by following features constructions:

• The presence of support legs, which visually and actually makes the sofa taller. A product on high legs can visually increase the area of ​​the room, on low legs, on the contrary, visually reduce.
• The presence of cushions on the seat. They add headroom for seating comfort. At the same time, the sofa can visually look low if the structure has a low back.
• The level of hardness of the filler. The sofa can be visually as high as you like, but if the seat filler is not rigid enough, it can easily slip down. Such a product cannot be called convenient.

Based on the listed features, we can conclude that when choosing a comfortable sofa, you must pay attention to all the nuances of the design. If the required parameters are not in the product passport, do not be too lazy to measure them yourself or check with our consultants. In the selection process, it is also important to rely on your own feelings, therefore, if possible, it is recommended to test the product personally - the network or lie on it.
