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 design, 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 sidewalls) look more compact and are suitable for small rooms. Their advantages include:

• ergonomics and compactness of the furniture item;
• stylish and original appearance;
• the ability to install soft ottomans or a coffee table on the sides of the sofa;
• lower cost of the product.

When choosing a sofa without armrests, it is worth considering that if the furniture is used as a sleeping place, then the 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 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 can be like on a spring block, i.e. with a spring mechanism and with a springless one:

• Bonnell blocks are classic and use dependent springs of 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 use a spring mattress, polyurethane foam, and coconut fiber at the same time. 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 You should limit yourself to more compact narrow models, while large and wide products look beautiful in spacious living rooms or bedrooms.

Fabric, leather, with combined finishing

Upholstery is selected depending on the stylistic direction of the room and the 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 a wide variety of colors, textures and patterns;
• velours. It has a soft and delicate surface. Its composition is dominated by natural and synthetic fibers that are resistant to deformation and fading under direct sunlight. 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 perfect 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 – 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

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:

1. The classic version (see photo above) is equipped with an extremely 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;
2. 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, wooden frame and velor upholstery cost from 5,000 rubles, which is quite inexpensive. The price for upholstered furniture from a well-known manufacturer with filling from independent spring blocks and higher quality upholstery will be 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.

Many models are equipped with additional accessories (footrest, linen drawers, armrests, tables). Each buyer decides which option to choose for himself, based on his needs, the characteristics of the room, the purpose of the furniture and his financial situation.

The cover is not removable. The inside of the case is stitched with padding polyester and decorative stitching. The sofa is equipped back panel at the head, which is made in the fabric of the armrests.

The filling of the mattress is the highlight of the sofa.
Sleeping area Provides comfortable daily sleep. The mattress has a high ability to restore shape, as well as increased resistance to changes in load on the sleeping area.

The filling of the mattress is multi-layered. The first layer is high-density polyurethane foam, providing moderate rigidity, so necessary for orthopedic sleep. Next - two layers of 5 mm each. Each one is made of environmentally friendly, durable, wear-resistant material - heat-pressed felt (thermal felt). Thermal felt is made from natural raw materials and laid in two layers to enhance the effect. Thermal felt - a material obtained by sintering synthetic and natural fibers (cotton threads and rags, wool tow, etc.) - ensures surface leveling and serves to ensure the hardness and strength of the mattress. The next layer is 30 mm. polyurethane foam of increased elasticity, which enhances the comfort of fit, but due to its optimal height is not subject to rapid deformation during operation. Next comes a layer of polyester fiber, which creates shape and adds softness and fluffiness. The sofa mattress is covered with a special cover. The inside of the upper cover is quilted with 300-density polyester fiber.

Mattress hardness: average.

The heaviest part of the sofa is frame. And it also has the greatest impact 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 in terms of specific gravity. The total weight of 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. A standard folding sofa with a birch frame will weigh from 60 to 90 kg. If we take all interior wood furniture materials, then birch can be called their golden mean in terms of price-quality ratio. Also, the best plywood for the bases and slats of sofas is made from birch.

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 you can play with the weight by reducing it as much as possible on all non-load-bearing structures - and then such a sofa can weigh 40 kg. Or, on the contrary, you can give the product solidity through wooden parts - and then the sofa will weigh 60-90 kg. In a word, with a frame made of chipboard, the weight of 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. 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!

The matter of relocation was touched upon. A small, cozy sofa, which the owner easily moved from place to place, was carried out by two brave guys in loader uniforms. The transportation was completed successfully, it’s time to pay for the work. And then it turns out that the fragile girl, without much effort, was dragging furniture weighing 150 kg. Incredibly, please pay the workers according to the “oversized heavyweight” tariff.

How much does a sofa weigh on average?

An approximate estimate of the weight of your favorite furniture will help you avoid such situations. There is no universal calculation formula, but by looking closely at the sofa you can get your bearings with an accuracy of up to a couple of kilograms. It is enough to pay attention to the following parameters:

• dimensions;
• frame material;
• upholstery;
• mattress design.

Based on the listed features, it is already possible to make a rough estimate.

Book

A classic sofa of this design is distinguished by the spaciousness of its drawers, high quality assembly and decent weight, which ranges from 75-110 kg.

A larger number is typical for three-seat furniture upholstered in heavy material, 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 of the total mass falls on it.

The book can weigh less due to the use of lighter materials. A frame made of pine or chipboard, minimal structural reinforcement and a foam mattress on a fiberboard backing are not particularly durable, but the weight of such products can even fall below the 75 kg bar.

Angular

The corner sofa has a more complex frame and, therefore, a decent weight of 100-160 kg.

Just like with a book, than better materials, the heavier the furniture. The heaviest structures are those with a built-in transformation mechanism. The easiest options are kitchen ones, unable to be transformed, made from cheap materials.

Ottoman

A small, cozy sofa without unnecessary problems. The 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 load-bearing bars and several reinforcing bars cannot pull any more. Even in combination with fiberboard sheets, upholstery and foam rubber.

How is the weight of a sofa determined, by what parameters

The hardest part of any upholstered furniture is the frame. The most common materials for its manufacture:

1. Steel structures are not weightless, but are recognized as the most reliable. If such a sofa turns out to be light, then it is made of aluminum. It's easy to verify this.
   The mass varies in weight depending on the type of wood. Long-lasting oak and beech are the heaviest. Birch is not much lighter. Pine weighs the least.
2. In terms of weight, chipboard and fiberboard occupy a middle position between pine and metal.

In addition to the frame material, it is necessary to pay attention to the design features. The more complex the sofa transformation mechanism, the more weight the furniture pleases the owners.
