Abstract
A cover, which fits over a cushion, has a top panel formed from a highly elastic fabric and bottom panel formed from a high friction mesh. The top panel easily conforms to the shape of the user's buttocks with exerting shear on the skin. The bottom panel stabilizes the cushion on a supporting surface by reason of substantial friction between it and the supporting surface.

In combination with a cellular cushion having a rectangular base and air cells projecting upwardly from the base to form an array of air cells in which the upper ends of the cells form a seating surface that will conform to the shape of a user's buttocks, a cover fitted over the cushion and comprising:
- (a) a top panel located over the upper ends of the cells and being formed from a highly elastic fabric;
- (b) a bottom panel located under the rectangular base and covering substantially the entire base, said bottom panel being formed from a high friction mesh, said mesh being flexible and having parallel ribs and thinner connecting segments extended between the ribs;
- (c) side panels located between and connected to the top and bottom panels at the peripheral margins of the top and bottom panels, said side panels being formed from a highly flexible but substantially non-elastic fabric, one of the side panels being divided into sections which are normally joined, but may be detached to permit the cover to be removed from or fitted over the cushion;
- and
- (d) the coefficient of friction between the mesh of the bottom panel and traditional cusion-supporting surfaces being substantially greater than the coefficient of friction between the side panels or top panel and such traditional cushion-supporting surfaces.
A cover for a cushion comprising:
- (a) a top panel positionable over the upper side of the cushion and formed from a highly elastic fabric;
- (b) a bottom panel positionable under the cushion and covering substantially the entire underside of the cushion, said bottom panel being formed from a high friction mesh, said mesh being flexible and having parallel ribs and thinner connecting segments extended between the ribs;
- (c) side panels located between and connected to the top and bottom panels at the peripheral margins of the top and bottom panels, said side panels being formed from a highly flexible but substantially non-elastic fabric, one of the side panels being divided into sections which are normally joined, but may be detached to permit the cover to be removed from or fitted over the cushion;
- and
- (d) the coefficient of friction between the mesh of the bottom panel and traditional cushion-supporting surfaces being substantially greater than the coefficient of friction between the side panels or top panel and such traditional cushion-supporting surfaces.
