The GRIT Freedom Chair has a 14-degree seat dump. This holds the rider in the seat when riding over uneven terrain. This wedge cushion can be used with the standard GRIT Freedom Chair cushion to make the seat more comfortable for riders who would prefer to sit on a more horizontal surface. The cushion sits on the seat and the wedge is aligned opposite the seat dump, cancelling most of it out. This cushion ships in addition to the standard cushion on the chair, so you would receive two cushions in total.
