**PURAP U-Float Liquid Layer Cushion for Tailbone & Coccyx Pain Relief – 20" x 18" x 1.5" – Orthopedic Seat Cushion for Office Chair, Car, Wheelchair – Pressure Relief for Sciatica & Back Pain**

Pain relief from coccyx, tailbone, ischial, sciatica, pregnancy, and back pain The PURAP Cutout cushion is a thin, low-profile, flexible cushion designed to provide relief from sitting and back pain. It helps eliminate high pressure points, effectively dissipates sitting pressure, and improves posture. It uses patented fluid 3D Flotation Technology which is used in high-end zero gravity chairs and the PURAP wheelchair cushion, which have been used by thousands of customers. . The PURAP cushion provides better pressure relief and comfort than memory foam and gel cushions Pressure comparison between a foam cushion and the PURAP cutout cushion Foam and gel cushions: They may feel comfortable initially but they don't effectively dissipate pressure. They 'pack-down' like springs and create high pressure points (hotspots) which cause pain, irritation of sciatic nerve, and cutoff blood circulation. Hotspots are indicated by red areas in the pressure mapping above. The PURAP cushion: PURAP's fluid 3D Flotation technology helps dissipates high pressure points over the whole cushion (you may see it ballooning at the edges). This eliminates high pressure points and irritation, and provides pain relief and comfort. . For coccyx, tailbone, and ischial pain Patients with coccyx pain can have extremely tender or sensitive coccyx. The cushion has a U-shaped cutout towards the back that helps eliminate pressure on the coccyx. Purap also helps dissipate pressure effectively to provide superior comfort. For sciatica, bottom numbness and lower back pain from sitting or driving Sitting long hours in an office computer chair or gaming chair, and driving long hours can create high pressure points, reduce circulation, and irritate the sciatic nerve. Purap helps eliminate these pressure 'hotspots' to prevent circulation cutoff, and also helps maintain a neutral spine position. This helps reduce bottom numbness and lower back pain. (For sciatica caused by injuries or other issues not related to sitting pressures, please consult your physician.) For pregnancy and post-partum sitting and back pain The Purap cushion helps reduce the pressure on the spine and maintain a neutral spine position and improve posture, which all help reduce back pain. It cradles the bottom and dissipates sitting pressure effectively to provide sitting comfort.
