Ergonomic Wheelchair Cushion. Not all seat cushions are suitable for wheelchairs but AUVON's. This sciatica pain relief cushion is specially made for wheelchair users. Based on ergonomic principles, the butt cushion features a front high, rear low design to relieve your lower body pressure and optimize your sitting posture scientifically (consult your healthcare provider before use).

Triple Anti-slip Designs for Enhanced Safety. The anti-slip performance of seat cushion for tailbone pain relief is significant for wheelchair users as we know. Designed to minimize the risk of sliding forward, this sciatica pain relief cushion adopts anti-slip bottom and hump design matching with the adjustable straps to offer stable support and enhanced safety for wheelchair users.

Breathable & Waterproof Performance. The orthopedic seat cushion features ventilated memory foam with air holes to reduce stuffy feelings and risks of pressure sore and ulcers from long sitting. The inner waterproof membrane prevents sweat or urine from eroding the memory foam. *To preserve the quality of the cover, please wash it separately on a gentle cycle with cold water (ideally between 65°F and 85°F) to prevent damage. After washing, please air dry to maintain its fibers. High temperatures should be avoided to ensure the cover's longevity and appearance, and do not wash memory foam.

Tailbone Pressure Relief & Care. The tailbone cushion features a U-shaped cutout to reduce tailbone compression and provide extra protection for your sciatic nerve. The memory foam cushion is the "long-sitting saver" to relieve the sitting discomfort of wheelchairs.

Wide Compatibility for Convenient Use. AUVON seat cushion for back pain (18" x 16" x 3") fits most wheelchairs around 17"-18" long and 16"-17" wide, and it can turn seats of scooters, office chairs, car seats, and dining chairs into comfortable seats. Warm reminder again: Attach additional straps for enhanced stability.
