The chair-bed is the most popular type of furniture for small apartments, and when choosing a model, the type of mechanism for the chair-bed used by the manufacturer plays a major role. This is the main parameter that you need to pay attention to if you want the purchase to please you and last a long time.
Mechanisms for a chair-bed differ in the degree of reliability and ease of use. Some of them are designed for daily use, some - for unfolding only from time to time. In addition, the mechanism for the chair-bed largely determines how flat the surface for sleeping will be. This is especially important if the furniture will be used as a permanent bed for one of the family members. The more even the surface is formed by the unfolded chair, the better the conditions for sleep will be, the stronger and healthier it will be.
Tip: If the chair-bed is used daily, it is recommended to purchase a special mattress for sofas (topper). It levels the surface of the chair-bed, smooths out irregularities and joints, prolongs the service life, and also gives the chair-bed orthopedic properties.
When unfolded, products equipped with this mechanism form the most suitable surface for healthy sleep. It is quite even, no gaps between the individual parts and height differences are observed. You can find on sale both models with armrests and without them - the latter have a greater width with the same overall dimensions, which is important for small apartments.
An accordion chair is assembled - two of the three parts, the headboard and the middle, rise and fold together, touching the bases and forming a back, and the footboard remains in a horizontal position. As a result, the backrest is very wide, especially if the bed has an orthopedic filling.
When laying out, the seat base is pulled towards itself, while additional sections are extended. The seat is turned over, getting a fairly flat bed.
The main disadvantage is the presence of gaps between the individual parts of the mattress. Another feature is the low height of the bed, usually it does not exceed 25-30 cm, which can be inconvenient for tall people and the elderly.
A part of the berth “emerges” from under the seat, while it is installed at the same height as the main seat.
To install the mechanism itself, a large space is needed, therefore, in chairs equipped with a "dolphin", there is usually no additional drawer for bed linen. There are gaps in the bed, which is a minus of these models. The height of the bed is standard.
The tick-tock chair-bed transformation mechanism works as follows: when the seat is extended, the back of the chair is turned over and lowered - this design allows you to place the model almost without a gap with the wall, which saves space.
Models of the “walking Eurobook” type do not slip on the floor, which allows you not to damage the floor covering.
The variety of models is not limited to the listed options, and below we will consider a few more popular mechanisms:
In models with a folding bed mechanism, the bed is removed from under the main seat. It consists of a frame on which the lamellas are fixed. It is one of the best mattress bases as it has orthopedic properties. On top of the slats, a mattress of increased rigidity, which has a significant thickness, is laid. There is no box for linen in such models, there is no place for it.
This chair-bed transformation mechanism allows you to get a surface from four separate parts. Usually, mattresses are used in the manufacture, which can be folded - when laid out, a rather comfortable bed is obtained.
If the model is made of separate parts, you will have to sleep on four joining surfaces, which is inconvenient. The problem can be solved by using a mattress topper. A significant drawback of the click-clack mechanism for chair beds is a small sleeping place, usually no more than 140 * 140 cm.
Of all the options listed for daily use as the main bed, the accordion can be considered the best. In addition to the fact that the bed turns out to be even and comfortable, of standard height and without gaps, this mechanism is also the easiest to unfold. Only a click-clack from a whole mattress, folding along four lines, can compete with it.
