The Jay Basic Wheelchair Cushion is a mildly contoured foam cushion that's designed to provide stability and comfort for a user with a flexible posture and low risk for skin breakdown. The durable, molded foam provides you with mild contouring that increases both sitting tolerance and postural stability. This cushion is especially great for wheelchairs with sling upholstery due to its beveled bottom that reduces the "hammocking" effect of upholstery - keeping the sitting surface level, which improves pelvic alignment over time. This cushion's cover is moisture resistant to help prevent stains and better manage incontinence. Also, the cover features a no-slip bottom to keep the cushion in place. Available in 4 different sizes.
