Say goodbye to uncomfortable seating with the Everlasting Comfort Office Chair Seat Cushion. Designed for people who sit for long periods throughout the day, our memory foam seat cushion for office chair is made of 100 percent pure memory foam that provides unmatched comfort and support. Our lumbar support office chair pad features an ergonomic contoured shape that cups the butt and thighs for a cradling effect that distributes weight and provides support where you need it most. The memory foam is heat responsive, using your body heat to adjust to your individual contours for a customized feel. We included a "U" shaped cutout to help relieve pressure on the tailbone or coccyx area, which can be sensitive and painful for some people. Our butt cushion for office chair protects you from the discomfort associated with sitting, providing pain relief for the legs, butt, tailbone, and lower back, including sciatica pain relief.

It fits almost any seat and can be used at the office, home, or wherever you may encounter a hard or weathered seat. The tailbone cushion's crystal velvet cover is both soft and breathable, enhancing cooling while you sit in comfort. The office seat cushion's cover is easy to remove for cleaning and is washer and dryer safe.
