Abstract
A mattress is supported on a flexible deck which is surrounded by and connected to a foldable frame. A back section of the frame is movable between a horizontal sleeping position and a vertical seating position. A supplemental back spring is attached to the frame and has a flex wire section and a collapsible section. The flex wire section provides horizontal support to the mattress in the seating position, and the collapsible section of the spring resists hammocking or sagging of the deck when the mattress is in the sleeping position.
