Hello Stepan!
When buying, you need to get information about the permissible load on the mechanism. This data is indicated in the description of the model, otherwise check with the seller. Ask what is the maximum weight that the sofa you like can withstand. In addition, it matters whether the furniture will be used daily or is it a guest option. Important Features when choosing a durable sofa, it is a strong frame, stable, unshaken legs and reliable mechanism transformations.
The choice of the mechanism for the transformation of upholstered furniture
- Withdrawable mechanism considered one of the most reliable and durable. It is designed for numerous transformations, suitable for everyday use. It's easy to unfold and put away. Under the seat is hidden a special belt loop, pulling on which, you will force the front part to move forward and the back to take its place. Models equipped with this mechanism, as a rule, 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. The improvement of the previous mechanism consists in the mechanical lifting of the seat above the floor as a result of the transformation of the sofa.
- "Click-clack" - sofas with this transformation mechanism are distinguished by the absence of cracks and depressions in the bed. In addition, they are more comfortable due to the choice of positions: "lying", "half-sitting" or "sitting".
- Might be worth considering 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 large weight, it is important and right choice spring blocks. In this case, "Bonnel" is recommended - in these blocks, the radius of support of the spring coil is successively reduced. As a result, the spring is easily compressed at the beginning of the load, and becomes tighter as the load increases. If your weight is more than 110 kg, you should carefully consider this option. Consider the disadvantage of this type of springs - they are interconnected. As a result, by pressing one spring, you act on others. Therefore, this kind of spring blocks do not adapt very well to the shape of the human body. independent block devoid of these shortcomings. But it is not suitable if the load on the furniture is above 110 kg.
How soft should your sofa be?
For bed you need to choose a harder surface. high density polyurethane foam makes the surface of the bed more resilient, which means it can withstand more weight. Compared to spring construction, PUF provides a stiffer surface.
As for durability, both options are encouraging. High-quality polyurethane foam is designed for a long service life. Spring packs are also quite durable if they are relatively expensive. Flooring good 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 must have metal mounts, plugs, supports, springs and buttons. Avoid plastic parts.
Sincerely, Galina.

Features of a set of upholstered furniture "Book 1"
- Frames of furniture products are made of plywood 15 mm thick, lumber pieces conifers(pine).
- The frames of the products are assembled on furniture staples 38 mm long by PREBENA, self-tapping screws (Germany).
- Sofa bed with storage capacity bedding under the seat. It is completed with two decorative removable pillows filled with elastic polyurethane foam and bulky “comfort” fabric.
- The folding part of the sofa bed is the Finca transformation mechanism. The transformation mechanism consists of two metal frames made of pipes rectangular section with lamellas made of curved plywood 8 mm thick, 50 mm wide. The frames are connected using locks of the "book" type on M6 bolts with nuts. Three-position locks are attached to the side walls of the container with M8 bolts and nuts.
- Unfolding the sofa bed into the "bed" position is carried out in next order: the seat of the sofa bed is lifted up until it clicks, then the backrest is moved to a horizontal position and the seat is placed in a horizontal position flush with the backrest. Sleeper 1900x1350 mm.
- Soft elements of the seat and back in the form of removable mattresses made of elastic polyurethane foam with high physical and mechanical properties, 100 mm thick. Covers are made of non-woven fabric No. 100 with zippers.
- The cover of the sofa bed is removable, duplicated with spunbond 200, common for the seat and back, stitched with decorative stitches.
- The cover is fixed at the junction of the back-seat with mattress covers and with the bases of the soft elements of the seat and back (lamellas) on a contact wide Velcro-thorn tape. On the reverse side, the cover is pulled together with elastic wide rubber 15-20 mm.
- The rear wall-curtain made of furniture fabric is sewn to the upper edge of the backrest and attached to the side walls of the box with tapes.
- contact "Velcro-thorn".
- Supports metal chromeplated 90 mm high.
Leisure chair
- Lounge chair with folding mechanism transformation "Fink". The mechanism of transformation is similar to the mechanism of transformation of a sofa bed, differs in the size on length - 600 mm.
- A lounge chair is similar to a sofa bed, only different in size.
pouf
- The basis of a soft element of a seat - rigid from a chipboard 16 mm thick.
- soft element the seat is formed from 120 mm thick elastic polyurethane foam and a spunbond layer.
The furniture has passed all the tests, confirming its environmental friendliness, suitability for use and safety. The furniture complies with the requirements of GOST 19917-93 and has a Declaration of Conformity. The manufacturer reserves the right to make design changes that do not impair quality characteristics and appearance products.
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 weight 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. The expected service life is 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 can’t really 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 you should pay attention 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!
