ABSTRACT:
A foldable sofa sleeper fixture comprises a rectangular metal frame having pivotally interconnected head, body and foot sections. That rectangular metal frame is characterized by side and end frame members and an all cloth deck supported by the frame members. The all cloth deck is made from woven polypropylene fabric material which is connected to the side frame members without any resilient connectors therebetween. This woven polypropylene fabric material is characterized by greater stretchability in the warp direction than prior art woven polypropylene fabric deck materials in order to facilitate this direct connection of the deck to the side rails of the frame without the presence of resilient connectors therebetween.
