Black gel memory foam thick cushion

Updated at 2026-09-10

This 4 in thick cushion combines the support of memory foam with the cooling properties of gel. The gel layer helps to regulate temperature, while the thick foam base provides deep cushioning for the tailbone and hips. It is sized at 19x17.5 in, offering a generous surface area for larger chairs or wheelchairs.

The non-slip bottom is a key feature, ensuring the cushion stays securely in place on various surfaces including smooth plastic or metal seats. A built-in carry handle makes it easy to transport between the car, the office, or home. The black cover is designed to be discreet and durable for everyday use.

The ergonomic shape is specifically intended to relieve pressure on the coccyx, making it a helpful tool for those dealing with chronic pain. The extra thickness provides more clearance from the seat base than standard cushions. This makes it a reliable choice for users who require significant impact absorption and support.
