Sofas are available in every home. Some use them as additional seats when guests gather, others purchase 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, materials of manufacture.
Among huge selection sofas, the most popular and common are folding models - books. They differ in functionality, aesthetics, ease of use and high technical specifications.
Types and features of book sofas
The peculiarity of the sofa-book is that when unfolding, its back leans back, and the seat, slightly moving forward, falls back onto the frame, while the process itself resembles turning the pages of a book. This is how it got its name. To decompose it, you need to make a minimum of effort and spend a few seconds of free time.
Photo: What a sofa book looks like (folded and unfolded) The main advantages of these models should be added:
- strength and reliability. This piece of furniture has stood the test of time;
- long service life of the transformation mechanism;
- practicality. Models are upholstered with various textiles: leather, jacquard, chenille;
- ergonomics. When folded, they take up little space;
- wide model range;
- affordable cost.
As for the varieties, the book sofas are equipped with: armrests, linen drawers, different types mattresses and fillers.
With or without armrests
Products with armrests are classic version, without them - to the modern. Products without armrests (without sidewalls) look more compact and are suitable for small rooms. Their benefits include:
- ergonomics and compactness of a piece of furniture;
- stylish and original appearance;
- the ability to install on the sides of the sofa soft ottomans or a coffee table;
- lower product cost.
When choosing a sofa without armrests, it should be borne in mind that if the furniture is used as a bed, then pillows will slide off it during sleep.
But, if there are small children in the family, it is better to choose furniture with soft armrests, as it is safer.
Armrests, in turn, are wooden or soft. Wooden handrails have:
- wear resistance and durability;
- naturalness and environmental friendliness;
- the presence of additional space for a laptop, tablet or any other items;
- ease of use.
Soft armrests are more whimsical in care. But they are pleasant to the touch, you can lean on them while watching a movie or a friendly conversation.
With a box for linen (storage system) and without a box
Most models of book sofas are equipped with additional linen drawers. They significantly increase the process of operation, as they have room for pillows, blankets, bedding sets and other things.
Some models are equipped with one capacious drawer, others - with several. Also boxes for linen, depending on the chosen model of furniture, differ in size and depth.
Linen drawers in book sofas can only be accessed in the disassembled position of the piece of furniture. Although there are models that always have access to them.
With independent spring block, with Bonnel spring block, springless
All book sofas are complemented by different types of filler. They can be both on a spring block, i.e. with a spring mechanism, and with a springless:
- Bonnel blocks are classic and use dependent springs large diameters. Such products are distinguished by an average degree of rigidity and a low orthopedic effect;
- mattresses with independent springs contribute to the complete relaxation of the muscles and spine. These products are practical, comfortable and durable;
- springless mattresses. They come with polyurethane foam (polyurethane foam), or are filled with latex, coconut fiber, etc. They have a high degree of rigidity and they belong to the economy class. Springless mattresses are not very durable, and when choosing, preference is given to models that use solid material.
Often on sale you can find products with combined fillers. In such sofas can be used and 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 that 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 - the buyer decides. Here, preference is given to more convenient and practical models. Also, when choosing a narrow or wide sofa, the area of \u200b\u200bthe room where it is installed is taken into account. For small rooms should be limited to more compact narrow models, and large and wide products look beautiful in spacious living rooms or bedrooms.
Fabric, leather, mixed trim
Upholstery is selected according to 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. Features a soft and delicate surface. Its composition is dominated by natural and synthetic fibers, resistant to deformation and fading under straight lines sunbeams. Velor is easy to clean, retains the brightness of the color for a long time, and does not lose its original qualities;
- flock. Imitates velvet or suede. Differs in softness, wear resistance and convenience in leaving. This is perfect option if pets live in the house;
- chenille Hypoallergenic and abrasion resistant material with a fleecy structure. Does not absorb odors, easy to care for.
- eco-leather. New generation material, outwardly similar to genuine leather. Differs in moisture resistance, elasticity, resistance to mechanical damages.
On a metal frame and wooden
Metal products are more wear-resistant and able to withstand heavy loads. Although most consumers prefer wooden frames made of pine, beech, plywood, chipboard. Chipboard and pine products - a budget option. It is unlikely to please consumers with a long service life. In the middle price category there are models whose frame is made of plywood or beech
The strength of the sofa frame directly affects its lifespan.
Photo: The principle of operation of the sofa-book transformation mechanism The sofa-book is equipped with a unique transformation mechanism that provides a smooth sleeping place. There are two types of layout:
- The classic version (see photo above) is equipped with extremely simple mechanism. It has only two moving parts - the back and the 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 expand it according to the same principle as described above.
Photo: Roll-out sofa-book A classic sofa-book should not be placed close to the wall, since when unfolding it will have to be moved 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.
In addition, it is worth noting that the Euro-models (unlike the "books") have a more even and comfortable bed, and the case itself is devoid of complex nodal connections, there is practically nothing to break. Therefore, the answer is, which is better - is obvious.
Standard sofa bed sizes
All book sofas differ in size, which directly depend on the number of seats. They are: two-, three- and four-seater. 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 place to sleep, as well as the height of the seat.

Depending on the length and width of the place to sleep when unfolded, the book is divided into a one-and-a-half-sleeping or double sofa. The dimensions of the bed at the sofa-book directly depend on its model.
Photo: Sofa book - unfolded dimensions of the bed Those who like to sleep in comfort should choose products with the maximum dimensions of a bed, 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 the sofa-book can be very different. Its weight is influenced by various factors: type of construction, dimensions, frame materials.
Classic book with roomy 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 substrate. Their weight can be less than 70 kg.
The 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.

There was a matter of relocation. A small, cozy sofa, which the hostess easily moved from place to place, was carried out by two brave guys in the uniform of porters. The transfer was successful, it's time to pay for the work. And here, it turns out that a fragile girl, without much effort, dragged furniture weighing 150 kg. Unbelievable, but if you please, pay the workers according to the “oversized heavyweight” tariff.
How much does a sofa weigh on average
A rough estimate of the weight of your favorite furniture will help to avoid such situations. There is no universal calculation formula, but looking closely at the sofa, you can navigate with an accuracy of a couple of kilograms. It is enough to pay attention to the following parameters:
- dimensions;
- frame material;
- upholstery;
- mattress design.
Based on these features, it is already possible to make a rough estimate.
Book
A classic sofa of this design is distinguished by the capacity of the drawers, high quality assembly and decent weight, which ranges from 75-110 kg.
A higher number is typical for three-seater furniture with heavy material upholstery, the frame of which is made of solid wood. Modern mattresses are relatively light, but if we are talking about the old "spring", then the lion's share total mass belongs to her.
The book can weigh less due to the use of lighter materials. Pine or chipboard frame, minimal structural reinforcement and foam mattress on a fiberboard substrate, they are not particularly encouraging, but the weight of such products can even fall below the bar of 75 kg.
Angular
The corner sofa is distinguished by the greater complexity of the frame and, therefore, a decent weight of 100-160 kg.
Like with a book than better materials the heavier the furniture. The heaviest are structures with a built-in transformation mechanism. The easiest kitchen, unable to transform, options from cheap materials.
Ottoman
A small, cozy sofa without unnecessary troubles. Ottoman weighs about 40-50 kg. And if the movers try to convince you that this is not true, just turn the sofa on its side and show its design. Well, 4 legs, 4 bearing and several reinforcing bars cannot pull more. Even in combination with fiberboard, upholstery and foam.
How is the weight of the sofa determined, by what parameters
The hardest part of any upholstered furniture is the framework. The most common materials for its manufacture:
- Steel structures are not weightless, but are recognized as the most reliable. If such a sofa turned out to be light, then it is made of aluminum. It is easy to verify this.
The array varies in weight depending on the type of wood. Durable oak and beech are the heaviest. Birch is not much lighter. Pine weighs the least. - Chipboard and fiberboard in terms of weight occupy a middle position between pine and metal.
In addition to the material of the frame, it is necessary to pay attention to the design features. How harder device mechanism for transforming the sofa, the more weight pleases the owners of the furniture.

The heaviest part of the sofa - frame. And she 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 quite 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 berth 150 x 200 cm can range from 70 to 110 kg. What does it mean? Heavy, reinforced in places of greatest load, the steel frame will indeed be very durable. If the sofa metal frame weighs 40-70 kg, this means that the frame is most likely not steel, but combined or even aluminum. And such a frame, of course, will not add any special strength. Moreover, ceteris paribus, a frame made of solid wood of any tree 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 solid foundation and a high-quality transformation mechanism, even the smallest of these weights is enough not to worry about the durability of the product.
Birch only a few percent inferior in density and strength to oak - and just as lighter than it. Standard folding sofa with a birch frame will weigh from 60 to 90 kg. If we take all internal 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 lamellas 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. Estimated service life - from 10 to 20 years, depending on the model and the thickness of the frame.
It is believed that the heaviest and, moreover, the most fragile sofas are made on a frame 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 strong, like oak, but it’s quite possible to play with weight due to its maximum reduction at all 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 of chipboard weight sofa does not indicate either its relative strength, or its absence.
In the same way, it is difficult to judge the strength of the sofa by the weight if the frame combined. And pine and birch are combined with chipboard very often, just like steel with aluminum. Such difficult cases attention should be paid to other parts of the product - to the thickness and "birch" of the base, to the additional support under it, to the quality of the armrests and spring blocks, and to the sofa transformation mechanism. Individually, these characteristics do not affect the weight of the sofa much, but in combination 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 couch and lay sumo wrestlers on it, then you need to choose not the most massive and heavy model, but the one you like and most comfortable. After all, probably, it was not in vain that she passed all the required strength tests and you also liked it for a reason!
