ABSTRACT:
A sofa sleeper foldable sofa bed assembly having pivotally interconnected head, body, intermediate and foot frame sections which are extendable to form a bed and foldable to form a sofa seat. Each frame section has a pair of opposed side rails and the head and foot frame sections have end rails connecting the opposed side rails. The frame further comprises a cross rail extending between opposed side rails of the intermediate frame section. In one preferred embodiment, a floating cross tube is spaced from and generally parallel the cross rail. The floating cross tube has two ends, each end of which is secured to the cross rail by a rigid wire hook. A plurality of transversely spaced longitudinally extending sinuous wire springs extend between the cross rail and the end rail of the foot section of the frame in one embodiment of this invention and between the floating cross tube and the end rail of the foot frame section in a second embodiment of the invention. The floating cross tube enables the sinuous wire springs to be stretched and become more rigid when the frame sections are folded into a sofa seat then when the frame sections are extended in a bed position.
