The Kensington ergonomic memory foam seat cushion provides maximum support and comfort. Its ergonomic design promotes blood circulation and reduces pressure on the lower back when sitting. The premium, high-density memory foam provides professional support and always returns to its original shape. Its durability has been proven in independent tests - it retains its thickness even after 80,000 uses. High-quality silicone anti-slip base prevents the cushion from moving. Removable cover for easy cleaning. Thanks to the carrying strap, you can take it with you anywhere - to the office, home, car or other locations.
