Abstract
A convertible seating unit has noncoplanar sleeper-base sections. A mid-seat deck is highest, a back deck slightly lower and a seat deck considerably lower. The relative heights of the decks and corresponding thicknesses of their respective cushions provide a sleeping support surface for comfortably supporting a person'"'"'s mass. With the unit in the sleeping configuration, the mid-seat deck is highest and its cushion thinnest (relative to those of the seat deck and back decks), and the seat deck is lowest and its cushion thickest.
