This cushion offers excellent support, stability, pressure relief and comfort for any wheelchair user. The waterfall front increases comfort and reduces pressure behind the knees. A soft easy-to-clean polyurethane cover provides multi-directional stretch and helps protect against shear force. Two-density foam construction gives a soft top foam at user contact points and a firm base foam for structure and support. Features a round bottom and coccyx cutout for improved positioning. Available with and without four-chambered QuadraGel, which increases comfort and support while reducing heat, and is particularly helpful for high-risk users. The cushions feature a strap and plastic buckle.
