Abstract
A bed frame for a sofa-sleeper including pivotally interconnected head, body, intermediate and foot sections, each having a pair of opposed side rails adapted to support an overlying link fabric frame and mattress, which are movable between a retracted position in which the bed frame is contained within the sofa frame of the sofa-sleeper and an extended position in which the bed frame extends outwardly to form a bed. The bed frame is provided with a U-shaped cross brace to enhance lateral stability which is pivotally mounted at each end to a side rail for pivotal movement between a position beneath the link fabric and mattress, in the extended position of the bed frame, so as to avoid contact with persons lying on the sofa bed, and a folded position wherein the cross brace is disposed immediately adjacent the link fabric with the bed frame in a retracted position within the sofa frame.
