Description
From the sellerThe Cushion Lab Ergonomic Coccyx Cushion Seat Cushion is a black XL cushion with a zip cover designed to provide ergonomic support for the coccyx (tailbone) while sitting. The adjustable zip cover allows for easy removal and washing, making it convenient for maintaining cleanliness and comfort. Created by the trusted brand Cushion Lab, this product is ideal for those looking to improve their posture and alleviate pressure on the tailbone while sitting for extended periods. Cushion Lab is the best one I tried for my sciatica. Used for a short time, but the next size down works better for me. The return window had past. Original cost $89 plus shipping. Size: 21” x 18”
