A seat cushion is provided including an integral gripping member that prevents the cushion from sliding during use. The gripping member attaches to the cushion by a connecting strap which therefore allows the gripping member to be selectively placed in contact with either panel of the cushion. Accordingly, either one of the panels may be exposed during use which allows the seat cushion to be constructed of differing materials, colors or patterns for the respective panels. Additionally, damage to one of the panels still allows the gripping member to be used because the cushion can be reversed to expose the non-damaged panel.
