Means of transformation for the sofa bed works as follows.

In a complex form, the sliding frame 1 is located inside the base frame 2. To transform the sofa into the "bed" position, first move the drawer 18, mounted on the sliding frame 1, forward, slightly lifting it from the latches 22, which protect the sliding frame 1 from spontaneous roll-out to the stop 29. The sliding wheels 1 provide smooth sliding with rubberized wheels 20 fixed in a metal cage 21 installed in front, as well as side rollers with a flange 28 mounted on bolts cantilevered and supported by guides 27 to the base frame 2, while access to the cushion storage box 40 formed by the sides 25 and the bottom 34 is opened. Then, the supporting rotary frame 3, on which there are holes 4 for attaching orthopedic armor plates, is lowered onto the base frame 2, which rotates on the axes rotation 36 in the arcuate slots 37 located in the brackets 38. Quick-release hooks 32, openings 31 in the sidewalls 25 of the base frame 2, simplify the process of assembly and disassembly and transfer of upholstered furniture. The welded metal frame 15 of the sliding frame 1, with holes 16 for fixing orthopedic armor located on it, is adjustable due to the grooves 14 located on the brackets 13 of the spring-lever lifting mechanism 12. The fluoroplastic washers provide smooth operation of the spring-lever lifting mechanism 12 (not shown shown). When lifting the welded metal frame 15, access to the second linen box 41 with a partition 30 in the middle. Boxes 40 and 41 are made of decorative durable material. The fastening of the drawer 18, made of decorative durable material, to the sliding frame 1, is carried out through the plate 19 with furniture bolts, which ensures the strength of the entire frame. The base frame 2 and the sliding frame 1 are made of a 20 × 20 profile pipe, which is powder coated and the open elements are closed with plastic plugs 30.

Transformation of the bed into the "sofa" position occurs in the reverse order.

Raise the support rotary frame 3, remove the pillows from the drawer 40. Then lift the welded metal frame 15 of the drawer 1 and fold the sheets into the drawer 40, lower the welded metal frame 15 and move the drawer 1 in the frame 2 until the rubberized wheels 20 are installed in the clips 22. Access to the drawer 40 is carried out both in the "sofa" position and in the "bed" position. In the "bed" position provides simultaneous access to two drawers 40 and 41.
