Abstract
Abstract A piece of furniture convertible from a couch to a chair is formed of a base having at one end an upwardly sloping portion and a back piece hinged at the upper end of the upwardly sloping portion and movable between a position in which it engages the upwardly sloping portion and is upright to form a backrest and a position in which it extends downwardly and rests on the floor. Two cushion members are provided, the first being hinged at the other end of the base portion and the second to the other side of the first cushion. These can be folded on each other and then onto the base portion to form a chair or seat, with the outer cushion resting against the upright back member.
