Abstract

A convertible couch or chair has a normally stationary main frame, a primary seat frame pivotal and slidable on the main frame, a secondary seat frame slidable on the primary seat frame, and a back pivoted on the main frame and on its primary seat frame. The primary seat frame slides at its rear end in upwardly and forwardly inclined guides and links connecting it to the back automatically displace this back on displacement of the primary seat frame away from the main frame from an up position behind a stack of two cushions supported on the primary seat frame into a down position level forming a horizontal continuation of the upper surface of the lower cushion. The secondary frame is formed as a bedding-storage compartment and when pulled drawer-fashion out of the pulled-out primary seat frame serves as a support surface onto which the upper seat cushion can be flopped.
