When I got a Studio apartment for room with an area of about 19 m2 was not able to come to the store and buy a universal or combined furniture. Had to do yourself. Particularly successful has turned the retractable bed: used it for 10 years. In contrast to the common schemes, with its vertical lift used horizontal, but without joints; simply trip standing on the floor of the bed to the side. This possibility is achieved through the bottom of the canister, the wall of which has a cylindrical rounding. This, of course, requires less effort and eliminates the need for devices necessary to balance the severity of the bed when lifting.
The chosen design was simple to manufacture, easy to operate: the bed is easily raised and lowered, and the canister in a vertical position serves as storage for bedding. His covers as if to form a shelf.
In the lowered position, the bed rests on one side of the pencil box, the other is hinged to it’s legs fused with felt or leather (not to scratch the floor), and when climbing they are cleaned in a special niche so that on the surface there is only chiseled decorative lining.
