WEDGE CUSHION with hard base - 16x16 in (40.6 x 40.6 cm)

A positioning cushion for those who slide forward in their chair. These polyurethane foam wedges are 4.5 in (11 cm) high at the front, tapered to 3/4 in (1.9 cm) at the back. All come with tie straps at the back to hold them in place. The hard based versions correct sagging sling seats in wheelchairs.
