ABSTRACT:
A sofa bed has a stationary framework and a foldable bed frame connected to and foldable into the framework, the foldable frame having an outer section connected to and pivotal relative to a body section, the outer section overlying the body section in the folded position of the frame to form a seat. The outer section has a plurality of individual seat support elements extending thereacross transversely to the sofa back. The individual elements are spaced apart in a direction parallel to that axis, and each of the individual elements is downwardly deflectable independently of the other when a person sits on said seat, and is arched so that a concavity is formed in the sofa form for the sofa cushions, and as that the mattress is compressed. A spring edge is mounted on and extends above a front rail of the stationary framework to form the front supporting edge of the seat.
