About this item

This U-shaped seat cushion is built to ease tailbone and lower back pressure, with raised sides that support your hips and a pre-shaped foam core that molds to your body. It measures 18"L x 16"W x 4"H and uses 4.3" thick bamboo charcoal-infused memory foam that holds its shape through long hours of sitting. The cover unzips for machine washing, and a non-slip bottom keeps it steady on any chair or car seat. Note: best for users under 200 lbs; heavier users should check the XL version.
