FOUR LAYERS OF SUPPORTIVE COMFORT: Experience unmatched comfort with our cushion’s four layers. The water-resistant cover is soft to the touch and is made with a non-slip base for greater stability. The machine-washable cover and waterproof seal enhance your ability to keep the cushion clean and safe for long-term use. A dynamic gel interior is encased in two highly-dense layers of foam, to distribute pressure and promote proper spinal alignment.
