The Professional™ Wheelchair Cushion provides exceptional pressure relief for users at risk of skin breakdown, or with a history of pressure injuries. A full 1 5/8" thickness of Akton® polymer provides effective weight distribution on a contoured or flat surface. The Professional™ provides an additional 50% cushioning against pressure, shear and vibration. This is significant for active clients using a power wheelchair who have concerns about bottoming-out and the potential effects of increased temperatures (due to foam insulation properties). Comes with Basic Cover.
