Abstract
The seating device has an elongated sack-like cover of a flexible material, such as an upholstery fabric, forming a cavity which is loosely filled with a freely flowable filler material, such as small spherical beads of expanded polystyrene. The cover includes a pair of generally vertical, opposed side panels, each of which has enlarged curvate end portions and a constricted intermediate portion, and an elongated center panel which is joined at its opposed longitudinal sides to the perimeter of the side panels to form a longitudinal, body supporting, upper surface having a generally convex enlarged end area adapted to serve as a backrest, another generally convex enlarged end area adapted to serve as a leg rest and a generally concave intermediate area adapted to support the derriere of the occupant. The contour of the supporting surface can be adjusted back and forth between a substantially upright sitting position and a substantially fully reclined position by selectively applying external pressure on one or more of the areas to cause the filler material to flow from and into selected areas and thereby alter the contour of the selected areas relative to one another.
