ABSTRACT:
An improved sofa-sleeper deck includes a number of serially interconnected welded grid panels secured to a foldable bed frame. Each panel is hingedly interconnected to the adjacent panel to form the deck of a sofa-sleeper structure. Each welded grid panel comprises a series of spaced, parallel, longitudinal wires and a series of spaced, parallel, transverse wires, all of which are welded at their intersections. A border wire extends around the perimeter of each wire grid panel and is welded at its intersections to both the longitudinal and transverse wires. In order to hingedly interconnect the panels, the longitudinal wires of at least one panel extend beyond the end of the border wire and are wrapped about the border wire of the adjacent panel.
