Abstract: A seat cushion cover (20) in combination with a sport seat cushion (22) includes a rectangular pocket (24) defined by a fabric upper panel (26) and a lower panel (28). The upper and lower panels (26, 28) are generally parallel to one another and are joined by side panels (30a,b) and an end panel (32). A fabric flap (34) extends from the upper panel (26). The flap (34) is adapted to retain the cushion (22) within the pocket (24) and provide for securing the cushion (22) on a stadium seat (54). The flap (34) foldably extends over an opening (33) of the pocket (24) and along a portion of lower panel (28). The flap (34) and the portion of the lower panel (28) are separated by a space for receiving the stadium seat bottom (56). The flap (34) is adjustably secured to the side panels (30a,b) with fasteners (42, 44, 46, 48, 50, 52). A resilient band (36) provides tension to retain the cover (20) on the seat bottom (56) when it is in its raised position.
