The ComfiLife Ergonomic Orthopedic Memory Foam Seat Cushion is a wonderful cushion which provides relief from back pain and sciatica. The cushion provides ergonomic support with high density memory foam and is so comfortable it will never flatten as it always holds its shape. I have been using this cushion on my office chair and it has really helped my lower back as it is so supportive. This seat cushion is perfect for travel and is wonderful for relieving sciatica and coccyx pain. The cover is made from a soft material with a rubber under side for a non-slip grip.
