It is difficult to imagine a modern house inwhich would not have a sofa. And if you come across such dwellings, then very rarely. Most living spaces necessarily have a kind of background-baron, a soft and cozy handsome man on which you can sit and lie down, and if necessary, turn it into a trivial bed. It is precisely this need that makes us choose a fold-out sofa, which during the daytime plays the role of an ordinary place for family gatherings and short rest, and at night magically transforms into a place to sleep. The magical power of such a transformation is the transformation mechanism, which can be different for fold-out sofas. And in order for the choice of a sofa to be successful, and the transformation process does not cause unforeseen (or, conversely, expected) difficulties, you need to know the principle of operation of these mechanisms. Let's figure out what the three main types of fold-out sofas are: "fold-out bed", "book" and a sofa with a roll-out mechanism.
Drawout sofa
The most famous representative of this speciesfolding sofas - a traditional sofa, familiar to us from Soviet times. In such a sofa, the sleeping area slides out (rolls out) from its lower part. To do this, it is usually enough to just pull on special loops. In the already mentioned sofa, pillows are placed on the lower extended part of the sofa, which act as its back when the sofa is folded. A modern model of a roll-out sofa is a "flash". In it, unlike a sofa, the back does not consist of pillows, but of a solid soft surface. When unfolding such a sofa, both the back and the seat are placed on the extended part. A corner roll-out sofa is called a "dolphin". It has a more complex design, consisting of three elements. The mechanism of its transformation works as follows. The seat of one component part of the corner is completely pulled out and turns the corner sofa into a rectangular bed. Sofas with a roll-out mechanism have their pros and cons. The obvious advantage of these sofas is a spacious sleeping area and compact size when folded. On the other hand, a roomy sleeping area makes such a sofa bulky when it acts as a bed. Therefore, for small rooms, sofas with a roll-out mechanism are hardly worth choosing.
Couch sofa
The folding mechanism of such a sofa itselfIt folds and unfolds together with the mattress. When the sofa is folded, it is hidden under the seat and to unfold it, you need to remove the cushions from the seat and pull the mattress up and forward. The mechanism for transforming sofa beds allows manufacturers to create a variety of original models. The most famous of them are the accordion, mixotoile (French folding bed), as well as American, Italian and Belgian folding beds. For example, accordions unfold like an accordion. After the seat is raised, the sleeping area itself (unusually easily) moves forward. These sofas are very compact when folded and at the same time have a full-fledged sleeping area. In addition, accordions are considered reliable enough for frequent use. The French folding bed unfolds in three steps. The American folding bed - in two, the Italian folding bed (the most expensive) is a double flip-over that folds out behind the back. The disadvantages of sofa beds include a somewhat tedious transformation process, as well as the fact that they do not have a drawer for storing bed linen.
Sofa-book
This sofa has the simplest foldingmechanism. And it works, as the name suggests, on the principle of a book. In order to unfold such a sofa, you need to lift the seat until it clicks, and then simply lower it down. An improved analogue of the "book" is the "click-clack" transformation mechanism. Its design provides for an intermediate (additional) position of the back, which makes it possible to be on the sofa in a semi-sitting (or semi-reclining) position. The "book" folding sofa is not considered the most reliable model. The locks of the folding mechanism in it wear out quickly, the "click-clack" mechanism is much more reliable. However, despite the simplicity of the mechanism, these sofas have significant drawbacks. Firstly, for the back to move freely, they cannot be placed close to the wall. Secondly, folding sofas do not differ in a variety of designer shapes. But their price is also low. The main and undeniable advantage of any folding sofa (regardless of the mechanism) is the possibility of its transformation. If the sofa is purchased to be used as a permanent sleeping place, then it is worth giving preference to domestic manufacturers. In terms of reliability and durability of mechanisms (oddly enough), they are significantly superior to imported analogues. The reason for this is probably the quality traditions of Soviet times, when unpretentious design and simplicity of construction were the key to durability. Folding sofas of imported production are more "presentable" or elegant, but are not designed for frequent unfolding. They are more suitable for use as an additional (guest) sleeping place. Therefore, when choosing a folding sofa, consider not only the operating principle of its mechanism, but also the intensity of the intended use. And what kind of sofa: a corner folding sofa, a large traditional one or a compact "baby" will take up space in your home, will depend on the volume of living space and your personal preferences. The main thing is that the sofa is comfortable, reliable and durable. The choice is yours!
