Abstract

A hollow-cylindrical air bag (1) is laid at the back, etc. of a chair, and an air cushion (2) is laid over the air bag. The angle of a backrest is freely adjusted by adjusting the amount of air filled in the air bag and the air cushion, and by adjusting the way of laying the air cushion and the air bag. The air cushion and the air bag are connected by adhesive cloth provided on them. To lie down on the chair, an air mattress (3) with a downward depression at its front end is laid under the air cushion so as to prevent the waist, coccygeal bone, etc. of a user from being in direct contact with an edge of the chair. The air mattress (3) is connected to the air cushion (2) using adhesive cloth provided on the air mattress (3) with the air bag (1) between them.
