Types of mechanisms for chair beds

Mechanisms for chair beds differ in the degree of reliability and ease of use. Some of them are intended for daily use, part - for folding only occasionally. In addition, how smooth the surface for sleeping will largely depend on the mechanism for the chair-bed. 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 the unfolded chair forms - the better the sleeping conditions 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 evens out the surface of the chair-bed, smooths out bumps and joints, extends the service life, and also gives the chair-bed orthopedic properties.

Accordion Mechanism

Unfolded products equipped with this mechanism form the surface most suitable for healthy sleep. It is quite even, no gaps between the individual parts and elevations are not observed. You can find on sale both models with and without armrests - the latter have a larger width with the same overall dimensions, which is important for small apartments.

An “accordion” chair is assembled - two of three parts, the head and middle, rise and fold together, touching the bases and forming a back, and the foot remains in a horizontal position. As a result, the back is very wide, especially if the berth has orthopedic filling.

Withdrawable mechanism

When laying out, the base of the seat is pulled over, while additional sections are pulled out. The seat is turned over, getting a fairly flat berth.

The main disadvantage is the presence of gaps between the individual parts of the mattress. Another feature is the small height of the bed, usually it does not exceed 25-30 cm, which can be inconvenient for tall people and also older people.

Chair bed "dolphin"

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 required, therefore, in chairs equipped with a "dolphin", usually there is no additional box for bedding. Slots in the berth are available, which is a minus of these models. The height of the bed is standard.

Tick-tock (Eurobook)

The mechanism of transformation of the chair-bed "tick-tock" works as follows: with the seat extended, the back of the chair is turned over and lowered - this design allows you to place the model with almost no clearance with the wall, which saves space.

Models like “walking eurobook” do not slip on the floor, which allows not to damage the floor covering.

The listed options do not exhaust the variety of models, and below we will consider several more popular mechanisms:

Cot

In models with a mechanism for a chair-bed "clamshell" the berth goes from under the main seat. It consists of a frame on which lamellas are mounted. This is one of the best reasons for mattresses, as it has orthopedic properties.On top of the lamellas, a mattress of increased rigidity is laid, which has a significant thickness. The box for linen in such models is absent, there is no place for it.

Click gag mechanism

This mechanism for transforming a chair-bed allows you to get a surface of four separate parts. Typically, in the manufacture of mattresses are used, which can be folded - when laying out, a rather comfortable bed is obtained.

If the model is made of separate parts, you will have to sleep on four mating surfaces, which is inconvenient. The problem can be solved using a mattress topper. A significant drawback of the click-gag mechanism for armchairs is a small berth, usually no more than 140 * 140 cm.

Of all these options for daily use as the main sleeping place, the “accordion” can be considered the best. In addition to the fact that the berth is smooth and comfortable, of a standard height and without gaps, this mechanism is also the easiest to fold out. Only a click-gag from a whole mattress folding in four lines can compete with it.
