Product details:

Bari-Foam Cushions feature temperature-sensitive visco-elastic foam that conforms to the patient to decrease pressure, prevent pressure sores and increase comfort. Three-part construction prevents bottoming-out. Top layer of visco-elastic foam reduces pressure. Middle layer of high-density foam adds comfort and cushioning. A firm foundation controls sling-seat hammocking. Fluid-proof, wipe-clean Low-Shear cover prevents skin-damaging friction. Safety strap keeps cushion securely in place. Choose a contoured base cushion for sling-seat chairs or a flat base cushion for solid-seat chairs. Anti-slip bottom for added safety. All cushions measure 4" high.
