Sofa sleeper deck with transverse slats

摘要

An improved sofa sleeper deck includes a number of pivotal transverse slats secured to a foldable frame. Each slat is pivotally coupled to a linkage so that the slats can pivot between vertical and horizontal orientations in the extended bed configuration or the collapsed sofa configuration, respectively. In the bed configuration, the vertical slats provide a stable rigid support deck for the mattress to avoid the problems of hammocking and the like associated with previous sofa sleeper decks. The slats in a horizontal configuration provide a comfortable cushion seating surface for the sofa in the collapsedapsed configuration and an enlarge cavity to accommodate a thicker or bigger mattress collapsed into the sofa.
