Abstract: A sofa sleeper comprises a stationary wooden sofa frame and a foldable sofa bed assembly mounted to the frame which is adapted to move between a fully folded or retracted position within the frame to provide a seat when used as a sofa and an extended unfolded position when used as a bed. The foldable sofa bed assembly includes pivotally interconnected head, body, intermediate and foot frame sections each including a pair of opposed side rails to which a wire fabric or plastic sheeting material is attached. The body frame section includes a pair of opposed cross tie members which extend between the side rails and are adapted to support a plurality of transversely spaced, longitudinal extending sinuous wire springs. Preferably, a rigidity bar extends between the cross tie members to maintain the cross tie spacing. The body frame section including the cross tie members and the longitudinally extending sinuous wire springs are located immediately beneath the mattress supporting fabric or plastic sheeting material so as to provide an improved cushion foundation when the sofa sleeper is used as a seating surface and an improved mattress foundation when the sofa sleeper is used as a bed.

Abstract: A sofa sleeper includes a stationary sofa frame having a front, back and opposed sides, and a sofa bed mechanism having pivotally interconnected head, body, intermediate and foot frame sections which are extendable to form a bed and foldable within the sofa frame to form a seat. The sofa bed mechanism is removably mounted to the sofa frame through the open bottom of the frame, and connectable thereto by interconnecting plate and bracket pairs, the plates being linked to the mechanism and the brackets mounted to the frame on each side thereof and releasably connectable together. The connection between the plates and brackets are provided by tapered rivets which extend from the brackets through L-shaped slots in the plates. A releasable lock holds the plates and brackets in connected position.
