| 摘要 |
A cover (A), which fits over a cushion (B), has a top panel (10) formed from a highly elastic fabric, bottom panel (12) formed from a high friction mesh, and side panels (14) connecting the top (10) and bottom (12) and formed from a flexible but non-elastic material. The top panel (10) easily conforms to the shape of the user's buttocks without exerting shear on the skin. The bottom panel (12) stabilizes the cushion on a supporting surface by reason of substantial friction between it and the supporting surface.
