There are sofas in every home. Some use them as additional seating when guests gather, others buy sofas so that they have something to relax and sleep on. Therefore, in addition to appearance, it is necessary to determine in advance their type of construction, dimensions, and materials of manufacture.
Among huge selection sofas, the most popular and widespread are folding models - books. They are distinguished by functionality, aesthetics, ease of use and high technical characteristics.
Types and features of book sofas
The peculiarity of a book sofa is that when unfolded, its backrest leans back, and the seat, moving slightly forward, falls back onto the frame, while the process itself resembles turning over the pages of a book. This is how it got its name. To unfold it, you need to make a minimum of effort and spend a few seconds of free time.

The main advantages of these models should be added:
- strength and reliability. This furniture has stood the test of time;
- long service life of the transformation mechanism;
- practicality. Models are upholstered in various textiles: leather, jacquard, chenille;
- ergonomics. When folded, they take up little free space;
- wide range of models;
- affordable price.
As for the varieties, book sofas are equipped with: armrests, linen drawers, different types mattresses and fillers.
With or without armrests
Products with armrests are classified as classic version, without them - to the modern. Products without armrests (without sides) look more compact and are suitable for small rooms. Their advantages include:
- ergonomics and compactness of the furniture item;
- stylish and original appearance;
- Possibility to install on the sides of the sofa soft ottomans or coffee table;
- lower cost of the product.
When choosing a sofa without armrests, it is worth considering that if the furniture is used as sleeping place, then the pillows will slide off while sleeping.
But, if there are small children in the family, it is better to choose furniture with soft armrests, as they are safer.
Armrests, in turn, can be wooden or soft. Wooden handrails have:
- wear resistance and durability;
- naturalness and environmental friendliness;
- availability of additional space for a laptop, tablet or any other items;
- ease of use.
Soft armrests are easier to care for. But they are pleasant to the touch, you can lean on them while watching a movie or having a friendly conversation.
With linen box (storage system) and without box
Most models of book sofas are equipped with additional linen drawers. They significantly increase the use process, since they have space for pillows, blankets, bedding sets and other things.
Some models are equipped with one spacious drawer, others with several. Also, laundry drawers, depending on the chosen furniture model, differ in size and depth.
Linen drawers in book sofas can only be accessed in the disassembled position of the furniture item. Although there are models that always have access to them.
With independent spring block, with Bonnell spring block, springless
All book sofas are complemented with different types of filling. They may be like spring block, i.e. with a spring mechanism and with a springless one:
- Bonnell blocks are classic and use dependent springs large diameters. Such products are distinguished by a medium degree of rigidity and a low orthopedic effect;
- mattresses with independent springs promote complete relaxation of the muscles and spine. These products are practical, comfortable and durable;
- springless mattresses. They come with PPU (polyurethane foam), or are filled with latex, coconut fiber, etc. They have a high degree of rigidity and belong to the economy class. Springless mattresses are not very durable, and when choosing, preference is given to models that use solid material.
You can often find products with combined fillers on sale. Such sofas can also be used spring mattress and PPU, and coconut fiber simultaneously. The composition can be very different. Therefore, before buying, you should sit on the sofa or several models you like in order to assess the degree of comfort and only then make a choice.
Narrow, wide
Which sofa to choose: large or compact is up to the buyer to decide. Here preference is given to more convenient and practical models. Also, when choosing a narrow or wide sofa, the area of the room where it is installed is taken into account. For small rooms it’s worth limiting yourself to more compact ones narrow models, and large and wide products look beautiful in spacious living rooms or bedrooms.
Fabric, leather, with combined finishing
Upholstery is selected depending on stylistic direction rooms and personal preferences of buyers. The main thing is that the product is easy to use and maintain. The following upholstery materials are considered the most popular:
- jacquard. Refers to semi-natural fabrics with high technical characteristics. It is quite dense, wear-resistant and resistant to negative factors. This fabric is available in great variety colors, textures and ornaments;
- velours. It has a soft and delicate surface. Its composition is dominated by natural and synthetic fibers, resistant to deformation and burnout under straight lines sun rays. Velor is easy to clean, retains its bright colors for a long time, and does not lose its original qualities;
- flock Imitates velvet or suede. It is soft, wear-resistant and easy to care for. This ideal option if there are pets living in the house;
- chenille Hypoallergenic and abrasion-resistant material with a fleecy structure. Does not absorb odors, easy to clean.
- eco leather. A new generation material that looks like genuine leather. It is characterized by moisture resistance, elasticity, and resistance to mechanical damage.
On a metal frame and wooden
Metal products are more wear-resistant and can withstand heavy loads. Although most consumers prefer wooden frames made from pine, beech, plywood, and chipboard. Products made from chipboard and pine – budget option. It is unlikely to please consumers with a long service life. In average price category There are models whose frame is made of plywood or beech
Its service life directly depends on the strength of the sofa frame.

The book sofa is equipped with a unique transformation mechanism that provides a flat sleeping area. There are two types of layout:
- The classic version (see photo above) is extremely equipped simple mechanism. It has only two moving parts - a back and a seat. To unfold the furniture, you need to lift the seat up and lower the back onto the frame. The seat rises until a click is heard. Then it goes down, forming a sleeping place;
- Roll-out book. The sofa is convenient because it does not need to be moved away from the wall. It is enough to slightly push the mechanism forward and unfold it according to a similar principle as described above.

A classic sofa book should not be placed close to the wall, since when unfolding it you will have to move it away each time.
What is the difference between a sofa book and a Eurobook?
The main difference between a simple sofa-book and a Eurobook is in the transformation mechanisms, i.e. folding methods.
Additionally, it is worth noting that Euro models (unlike the “book”) have a more level and comfortable sleeping area, and the body itself is devoid of complex node connections, there is practically nothing to break. Therefore, the answer, which is better, is obvious.
Standard sizes of a sofa book
All book sofas differ in size, which directly depends on the number of seats. They come in two, three and four seater types. The seats in them can be of any size, since there are no specific standards here.
When choosing a sofa, its width, depth and height are taken into account. An important parameter is the size of the sleeping area, as well as the seat height.

Bed size
Depending on the length and width of the sleeping area when unfolded, the book is divided into a single or double sofa. The size of the sleeping area of a book sofa directly depends on its model.

Those who like to sleep comfortably should choose products with maximum sleeping space dimensions, for example, 140x190 or 142x200 cm.
Seat height
As a rule, the height from the floor to the top of the seat is from 35 to 50 cm.
How much does a sofa book weigh on average?
The weight of a book sofa can be very different. Its weight is influenced by various factors: type of construction, dimensions, frame materials.
A classic book with spacious drawers for three seats will weigh up to 90 kg. The lightest in weight are models with pine frames and foam mattresses on a chipboard backing. Their weight can be less than 70 kg.
Average weight of a sofa book: 50-85 kg.
The cost of a book sofa depends on the type of its design, materials of manufacture, brand, transformation mechanism, dimensions. The most simple models economy class with polyurethane foam filling, on wooden frame and velor upholstery cost from 5,000 rubles, which is quite inexpensive. Price for upholstered furniture from famous manufacturer with filling from independent spring blocks and higher quality upholstery it will cost around 15,000 rubles and more.
In conclusion, it is worth noting that book sofas are universal furniture pieces. They are suitable both as an extra bed and as just sitting places. This furniture goes on sale in a huge assortment. Manufacturers produce them various types designs, dimensions, materials of covers and fillers.

The heaviest part of the sofa is frame. And she also provides greatest influence on the strength of the product. Therefore, it may seem that the heavier the frame, the stronger the sofa. However, this is not entirely true. Strength is determined not only by the weight of the frame, but by the material from which it is made.
Steel frames are the heaviest specific gravity. Total weight a standard sofa on a steel frame with a sleeping area of 150 x 200 cm can range from 70 to 110 kg. What does it mean? A heavy steel frame reinforced in areas of greatest load will indeed be very durable. If the sofa is on metal frame weighs 40-70 kg, this means that the frame is most likely not steel, but a composite one or even aluminum. And such a frame, of course, will not add any special strength. Moreover, all other things being equal, a frame made of solid wood will be preferable in a similar sofa.
Oak and beech The frames are also quite dense and heavy. In luxury models, the weight of a sofa with such a frame can exceed 100 kg. But in the middle class standard sofas with oak and beech frames weigh from 65 to 95 kg. And with a good foundation and a high-quality transformation mechanism, even the minimum of these weights is enough not to worry about the durability of the product.
Birch It is only a few percent inferior in density and strength to oak - and just as much lighter. Standard folding sofa with a birch frame it will weigh from 60 to 90 kg. If we take all the interior furniture wood materials, then birch can be called their golden mean in terms of price-quality ratio. It is also made from birch best plywood for bases and slats of sofas.
Pine– a very common and not the worst version of the frame. Less durable than birch, but more decorative. Sofa beds with pine frames weigh from 50 to 85 kg. The expected service life is from 10 to 20 years, depending on the model and the thickness of the frame.
There is an opinion that the heaviest and most fragile sofas are made on a frame made of Chipboard. And this opinion would be correct if it were not for the desire of manufacturers to make such cheap furniture still attractive to buyers. You really can’t make it as strong as oak, but it’s quite possible to play with the weight by reducing it as much as possible at all times. load-bearing structures– and then such a sofa can weigh 40 kg. Or, on the contrary, you can give the product solidity due to wooden parts– and then the sofa will weigh 60-90 kg. In a word, with a frame made of Chipboard weight the sofa does not indicate either its relative strength or its absence.
In the same way, it is difficult to judge its strength by the weight of a sofa if the frame combined. And pine and birch are combined with chipboard very often, just like steel and aluminum. In such difficult cases you should pay attention to other parts of the product - the thickness and “birch-likeness” of the base, additional support underneath, the quality of the armrests and spring blocks, and the sofa transformation mechanism. Individually, these characteristics do not affect the weight of the sofa much, but together they can increase or decrease its strength, relatively speaking, from chipboard to birch or vice versa.
In general, we can say that if you are not going to jump on the sofa and put sumo wrestlers on it, then you need to choose not the most massive and heaviest model, but the one you like and most comfortable. After all, it’s probably not in vain that she passed all the required strength tests and it’s not in vain that you liked her either!
Hello, Stepan!
When purchasing, you need to obtain information about the permissible load on the mechanism. These data are indicated in the model description, otherwise check with the seller. Ask what is the maximum weight the sofa you like can withstand. In addition, it matters whether the furniture will be used daily or is a guest option. Important Features when choosing a durable sofa, it means a strong frame, stable, non-wobbly legs and reliable mechanism transformation.
Choosing a mechanism for transforming upholstered furniture
- Roll-out mechanism considered one of the most reliable and durable. It is designed for numerous transformations and is suitable for everyday use. It is easy to unfold and put away. There is a special belt loop hidden under the seat; by pulling it, you will force the front part to move forward and the back to take its place. Models equipped with this mechanism usually have a spacious and flat sleeping surface. When folded, they take up little space. This sofa can be installed close to the wall.
- "Tick-tock" is an improved and modernized "Eurobook". The sofa mechanism extends the seat and reclines the backrest. An improvement on the previous mechanism consists of mechanically lifting the seat above the floor as a result of transforming the sofa.
- “Click-clack” - sofas with this transformation mechanism are distinguished by the absence of cracks and depressions in the sleeping area. In addition, they are more comfortable due to the possibility of choosing positions: “lying”, “half-sitting” or “sitting”.
- It might be worth considering the option corner sofa- the mechanism of such furniture is little involved, and since this part is one of the most vulnerable, a static sofa is more durable.
Spring blocks and heavy weight
For a person with a lot of weight, it also matters right choice spring blocks. In this case, “Bonnel” is recommended - in these blocks the radius of the spring coil support is consistently reduced. As a result, the spring is easily compressed at the beginning of the load, and becomes tighter as the load increases. If you weigh more than 110 kg, you should carefully consider this option. Consider the disadvantage of this type of springs - they are interconnected. As a result, when you press on one spring, you also affect the others. Therefore, this type of spring blocks does not adapt well to the shape of the human body. Independent block free from these shortcomings. But it is not suitable if the load on the furniture is above 110 kg.
How soft should your sofa be?
For a sleeping place you need to choose a harder surface. High density polyurethane foam makes the surface of the sleeping place more elastic, which means it can withstand more weight. Compared to the spring design, PPU provides a more rigid surface.
As for durability, both options are encouraging. High-quality polyurethane foam is designed for a long service life. Spring units are also quite durable if they are relatively expensive. Flooring nice sofa must last at least 5 years. Its durability is affected by the quality of materials and operating conditions.
And finally, pay attention to the fittings - a reliable sofa should have metal fastenings, plugs, supports, springs and buttons. Avoid plastic parts.
Best regards, Galina.
