Abstract
A convertible couch bed that consists of a frame (20) that has a pair of opposed ends (22) with each end having a horizontal upper surface (24), an arm (26) and a plurality of legs (28). The frame includes a pair of lower longitudinal supports (30) and a upper longitudinal support (32) attached between the ends. A mattress support structure (34) is positioned between the ends and sustained by the lower longitudinal supports and a mattress (36) is positioned on the support structure forming a comfortable seat for sitting on the front portion. An upholstered top (38) covers the rear portion of the mattress and is attached to the frame with a piano hinge (44). An upholstered back (48) is attached to the top allowing the back to fold upward in accordion fashion and rest upon the frame thereby permitting conversion of the couch into a bed by exposing the entire mattress therefore forming a bed suitable for sleeping. A second embodiment differs in that the mattress has two separate sections hingeably attached together such that when they are pivoted side by side in a flat position they form a king size bed.
