Backrest, seat, legs, armrests... What should they be like so that you can sit comfortably on the sofa? How to choose comfortable sofa, and which sofas are considered comfortable?
- 1 of 1
On the picture:
The most comfortable sofas-transformers. They allow you to fix the desired angle of inclination of the backrest or armrest. In some models, the armrest can be installed almost vertically. You can increase the height of the backrest with the help of a retractable headrest. Sometimes it hides inside the back frame in its own “pocket” and in order to push it out, it is necessary to remove the pillows and unscrew the hinges. Other manufacturers offer a composite pillow: top part the backrest is lifted and fixed on metal rods. The most convenient (and more expensive) option is the "wrapped" edges of the back cushion.

1 For home or office?
Determine the "terms of duty" of the sofa. This will help you choose the model of the desired shape.
If you are going to watch movies reclining, you need a completely different sofa than if you were planning to receive visitors at the office reception. For negotiations, models with swivel elements of the back of the sofa are suitable: they are indispensable if you have to talk for a long time, sitting half-turned - facing the interlocutor. On an ordinary sofa, the back without support will get tired, and a sofa with a mobile back will allow you to take a comfortable position. A compromise option: rounded island-type models and sofas with "notches" under the back of each seated person.
For sleep: decide if you need a guest sofa bed option or a transformer designed for daily use. Choose - an inexpensive traditional model or a sofa with an unusual mechanism.
2 High or low?
The standard height is approximately 42 cm from the floor. This rule is true for the vast majority of models. But some factories allow you to order comfortable sofas of the seat height you need. Surprisingly, even a difference of 2 cm can become noticeable: the knees stop rising unnaturally, nothing presses on the diaphragm.
How to choose a sofa for an elderly person? It is better to purchase a model with the highest possible seat: it is more difficult to get up from a low one.
3 Hard or soft?
Everything is subjective. Do not listen to advice - trust your feelings. Remember: the harder the pillow filling, the longer it will last. For greater softness, a layer of synthetic wool (dacron) or elite duck feather / down is added to the PPU layer. However, after sitting on such pillows, characteristic “hitches” remain. Annoys? Go for sofas with down pocket technology. By analogy with mattress springs, soft fluff and feathers are placed in individual envelopes. With point compression, they quickly restore their original shape.
4 Backrest height and seat depth.
- The traditional back height is equal to the depth of the seat.
- High back - at the level of the back of the head and above. Soft sofas with a high back and regular seat depth are designed for “correct” sitting (the back is tightly pressed against the back). The depth of the seat can be 60 cm, which corresponds to the length of the thigh of an adult. Deeper models (from 70 cm or more) with such a high back already require an additional pillow under the lower back.
- Low back - at waist level. As a rule, such a sofa has a seat of incredible depth - up to 100-125 cm. It allows you to take a “reclining” position on the sofa.
5 About compromises.
How to choose a sofa if family members have different preferences: one likes to lie down, and the other likes to sit upright? Look for a compromise solution: you can choose a sofa with a seat retractable forward (increasing depth) and / or a rising-falling back. You can also stretch your legs on the couch module, which is part of the corner sofa. Another option is to choose a sofa, from under which the footboard extends (unlike a separate pouffe, it does not take up extra space). Remember that on soft sofas you can sit not only across, but also along: lean your back on the armrest.

Optimal dimensions of the sofa
The main structural element of any upholstered furniture is its frame, which is made in accordance with the design features and taking into account the anatomical structure of the human body. The materials for the manufacture of the frame are solid wood, chipboard, metal structural elements, plastic.
To provide an attractive appearance and ease of use, the frame has a filler and upholstery. As a filler, spring or springless blocks, allowing you to give the sofa the necessary elasticity. The spring block is covered with upholstery on both sides. The lower upholstery provides high tear strength, while the upper upholstery gives the sofa an attractive appearance.

For a sofa to be comfortable, its dimensions must be determined by medical standards and anthropometric values. Too high or low furniture can not only spoil the aesthetic impression with incorrect proportions, but also lead to discomfort and even back pain. The standards by which all furniture products are created are designed to protect against such troubles.
What is the standard height of the sofa from the floor
By accepted norms the sofa seat should be located at a distance of 42 cm from the floor. It is permissible to change this value within 35-48 cm.
Important! Materials can affect the height of the seat: if the upholstered part of the furniture is stuffed with synthetic down or other air filler, the height can reach 50-55 cm - sitting down, a person will push through the filling with weight, and the landing site will drop to the prescribed 40-45 cm.
When choosing, you can take into account the characteristics of health and age: older people with sore joints and backs are more comfortable with a high and hard sofa: it is easier to sit on it and easier to get up. It is better for children to choose a product with a low seat in order to climb onto it without the help of adults.
A big role is not only the seat, but also the back. Her standard size- 90 cm. Fluctuations within 20 cm up and down are permissible, they depend on the design of the sofa, the number seats and features of the room. The back should not overlap the window sills - it should go flush with them or be lower. 
For reference! Furniture with high backs and soft headrests helps to relax the muscles and take the most comfortable posture, however, such products are only suitable for spacious rooms, in small rooms they clutter up the space, “eating” it. On the contrary, in large rooms small sofas dissolve, get lost, which can create a visual chaos of objects scattered here and there or bring a feeling of insecurity.
To make the product as comfortable as possible, other parameters should be taken into account:
- seat depth simple sofas- not less than 50 cm;
- depth of sofa beds - at least 70 cm;
- the height of the armrests from the seat - 12-35 cm;
- the length depends on the type of sofa and can reach up to 3 m.
Length may vary depending on design features products. So, if the sofa does not unfold, but is characterized as suitable for sleeping, then the seat must be at least 1860 mm. If a folding mechanism is provided, then the length of the sofa in assembled form can be less - from 700 mm, while the size bed must also be from 1860 mm.
How to measure the standard height of the sofa from the floor
To determine the exact dimensions of the product you like, the measurement must be carried out directly from the floor. The beginning of the ruler or tape measure should be pressed to the floor surface next to the furniture, holding measuring tool strictly perpendicular. Measure to the top edge of the seat if you are measuring the seat, or to the top edge of the backrest if you need to determine overall height. If the backrest includes pillows, then measurements should be taken to their top.
Important! However, the armrests are already measured from the top of the seat, from the middle of its depth - where it is pressed through the most. 
The best sofas with a standard height from the floor
Although the gold standard is a seat height of 42 cm and a back of 90 cm, furniture with such parameters will not necessarily be the best. When choosing a product, you need to consider:
- room dimensions;
- the number of people who will sit at the same time;
- purpose of use.
Depending on these criteria, sofas are:
- direct double or triple;
- corner triple and quadruple;
- couch;
- modular;
- folding.
Straight double products on average have a length of 2-2.5 m with a standard depth and height. Average triple options range in length from 2.5-3 m. The choice here depends on the parameters of the room. 
Corner sofas are often larger, as a rule, they have the highest back - up to 110 cm. They are well suited for spacious rooms where all households and guests gather. Their width reaches 100 cm, the longest side is up to 3.5 meters.
Often, corner products are made modular - they consist of separate parts that are connected to each other. Modules are different sizes, among them can be both folding and non-folding. This option is ideal for people who are accustomed to changing the situation - rearranging the components in places, connecting or pushing them apart, you can completely change the interior. The main thing is to make sure that the backs do not cover the windows.
If you need a sofa on which only one person will sleep, a daybed can be an ideal option. It expands only along, so it does not need a lot of space in front of it. Its length can be from 130 to 210 cm. 
A transforming sofa can present a particular difficulty in choosing. Some models are laid out according to the type of English or french cot, the sleeping place in them has two or three additions, and in order to accommodate it, the back is made high, about a meter. If you need a low back, you can choose a roll-out type option (dolphin, accordion, etc.), their seat is formed by pillows that are removed when unfolded. When choosing a folding model, you need to take into account the height of the bed, it can be low - 20-40 cm, standard - 35-45 cm and high - more than 45 cm.
However, a sofa that is matched to a person’s height will be truly ideal. For children, a length of 1300 mm may be enough, for a person with an average height - 1860 mm, for tall people - 1900-2000 mm or more. In this case, the standard depth of 700-800 mm must be observed. The most important thing to focus on is your own feelings, because the main goal of any sofa is comfort.
Assuming to purchase such an interior item as a sofa, the buyer will definitely focus on one of the main parameters when choosing it - size. Many people buy upholstered furniture, intending to use it as a bed. Therefore, in order to pick perfect option, it is also important to take into account the parameters of the room where the furniture will be located.
Features and Benefits
Before you buy a sofa, you need to decide on its functional purpose. When using furniture as an additional place to sleep, it is necessary to take into account its transformation (transformation) into a bed. Sofas can be classified according to their size according to their shape and the way they are laid out. Based on this, the form distinguishes:
- corner
- Direct
- Modular
- Island
Another sign of the classification of sofas is the presence or absence of a transformation mechanism. In modular and island sofas, such a mechanism is not provided, however, angular and straight models suggest both the presence of a transformation device and its absence.
In terms of size, non-folding sofas have compact dimensions and enough low price, however, they are less functional and adapted only for sitting. Such models are perfect for the kitchen, not large living room as well as an office.
If you plan to use the sofa as a place to sleep, you should pay attention to folding models, which are highly functional, but have larger overall dimensions than in non-folding products. Also, buyers will be pleased with the presence of a linen box in some models, which will become an additional niche for things. However, it should be borne in mind that this furniture is less mobile, as well as permanent use the mechanism of transformation into a bed leads to its rapid wear. Therefore, the choice of the folding method is one of the decisive factors when buying a sofa, as well as determining the necessary parameters.
When preparing for the purchase of a sofa, each buyer individually highlights the main and secondary criteria, with the help of which he will be able to choose the ideal option for himself.
corner
This type of sofa, like a corner sofa, has the largest dimensions due to its shape and is suitable only for a spacious room. In advance, you need to consider how much space the sofa occupies in the unfolded state so that it does not block, for example, a passage or a chest of drawers. The corner side serves as an additional couch, on which you can either sit or reclining. Often this part is used as a place for reading, since a bedside table or a floor lamp can easily fit on the side. In this type, a large linen box is provided, which will become an additional niche for both bed linen and any other things.
The dimensions of such products are quite diverse - from 140 cm to two meters or more, and the depth, on average, is 60-80 cm. It all depends on the transformation mechanism. In such models, such folding methods are provided as "dolphin", "puma".
When ordering this type of sofa, the buyer is also given the opportunity to choose a design that provides for the presence of armrests or a variant in which this element is absent.
Direct
When choosing straight sofa It is worth considering the room where it will be installed. For the kitchen, an oversized option will be an excellent choice, which will serve as an additional interior decoration. When choosing a sofa in the living room, the estimated number of guests is taken into account, so the designs are selected more spacious. The parameters of furniture are selected based on the desire of the client - from 130 cm and above, depending on its purpose. A bed in straight models is provided both along and across, which depends on the way it is turned into a place to sleep.
The practicality of sofas with a mechanism such as "book", "click-clack", "accordion" is that when unfolded, they increase exactly twice, without taking up extra space. And, for example, roll-out sofa type "dolphin" or "cot" assumes the presence of a perpendicular bed, occupying a fairly large space in front of the sofa. positive trait the latter is the small width of the structure when folded.
Sofas consisting of several modules, are a godsend for people who like to often rearrange furniture, because such a sofa will not only allow you to move it without problems, but also change its shape. These models are available in different overall dimensions, it all depends on the number of modules. The disadvantages are the high cost of such furniture, as well as the lack of a bed.
All modern sofas differ in comfort and functionality, but do not forget that the main thing when buying is to choose correct parameters upholstered furniture to purchase the perfect option for the room. Equal are the materials used for upholstery, as well as the filler of the sofa. They must be safe, high quality and durable.
Dimensions
Having chosen the shape of the sofa, it is necessary to correctly determine the parameters of the future acquisition, taking into account the size of the area on which the furniture will be installed, as well as the mechanism for its transformation into a sleeping place. Each type has several dimensions. For example, corner models most often made with standard width bed from 140 cm to 200 cm, depending on the number of people who will use such a product as a place to relax. Since designs with an angle have two straight parts, the parameters of both must be taken into account, where most often the longest part can reach 180 cm in length. As for the depth of the sofa, models with a depth of 70 cm are considered the most comfortable.
Most often, direct models of sofas are produced with standard parameters, but in the case of purchasing furniture for custom room The order is made according to individual measurements. However, it is worth knowing that the price of such a product will be an order of magnitude higher than the rest. For example, if desired, Personal Area you can order an exclusive model in leather upholstery, which will only emphasize the refined taste of the owner.
Depth in straight models is one of the most important parameters. You should also consider not only the amount of space that the sofa occupies when folded, but also when unfolded:
- In sofas such as "book", "accordion", where the bed is supposed to be along, standard length product depends on its destination. For the kitchen, a sofa with a length of 140, 150 cm will be sufficient. However, for big family permissible is the length of the product 160, 180, 190 cm. For big room the size of the product can be more than 2 meters, and the depth of the sofa - from 60 cm to 80 cm.
- When buying a sofa with a transformation mechanism, providing for the presence of a perpendicular place to sleep, it is important to consider its purpose. For example, the option for guests can be small - 100-120 cm wide, and 170-190 cm long. Meanwhile, assuming to use it as a double bed, you should pay attention to models with a length of 190 cm to 200 cm and a width of 130- 140 cm.
- It is also worth noting that to the children's room the sofa can be purchased without a transformation mechanism, as it may not be needed for a child. If the choice is stopped on a sofa that unfolds forward, it should be borne in mind that its length can reach 170 cm. Models of the “book” type can reach 2 meters in length, and in some cases even 3 meters.
- In models consisting of several modules, the size will depend on the shape of the sofa. The parameters of each module can vary from 50 cm or more.
