The liquid gel in the core allows for unrivaled pressure distribution across your bottom. Standard foam cushions simply provide a thin layer of padding while you are sitting. In this cushion, the internal fluid allows pressure to be moved from sensitive, high-pressure regions, like the coccyx and tailbone, to regions with less pressure. The removable cover features a nonslip base for added stability and is machine washable for easy cleaning. Simply remove the cover with the premium, durable zipper. Durably made, the cover will last for hundreds of washing cycles. Designed with medical-grade use foam, the cushion is also perfect for anyone who sits long hours at a desk or workstation. With an ideal balance of supportive foam and contouring gel, this versatile cushion will make sitting comfortable again.
