Wheelchair Seat Cushion 18x16x3"

Updated September 5, 2026

New. AUVON Wheelchair Seat Cushion 18x16x3" Brand AUVON Model SC1111 Amazon Product B0B82C3GRK Secure and Safe. To improve the safety of users in the wheelchair for daily activities, we designed a non-slip bottom and added a detachable strap to help fasten the wheelchair cushion in the wheelchair or other chairs. Superior Memory Foam. As prolonged sitting increases tailbone pressure, this chair cushion uses superior memory foam, which better responds to your body heat, evenly distributes weight and relieves your tailbone pain and spinal pain. Waterproof & Breathable. The cover was strategically designed with a layer of waterproof membrane, which protects the memory foam from sweat or urine and can be removed for machine washing (do not wash the memory foam). The butt cushion also features vent holes that allow for ample airflow and never trapped body heat. Ergonomic Design. The unique U-cutout design floats your tailbone and hence alleviates pressure and minimizes coccyx pain. The slope and contoured surface shapes your lower body while providing support for your thigh with optimal comfort Built for Daily Seat.
