ABSTRACT:
An improved sofa-sleeper structure having a foldable bed frame, the bed frame including a cloth front deck and a cloth rear deck. The cloth decks are fixed one to the other, e.g., by stitching, at their adjoining edges, and are attached by tension springs to the bed frame. A tensioning device extends between side members of the bed frame in the area where the front and rear decks are fixed together, the tensioning device maintaining the front deck relatively taut when the bed frame is folded into the sofa attitude, thereby aiding in establishing a spring surface for the sofa's cushions.
