Ergonomic Seat Cushion

FlexiSpot seat cushion features an O-shape not-flat design that eases pressure on the tailbone perfectly, to support the buttocks and upper thighs for proper weight distribution. You could carry it around and place it anywhere you sit. It is made with 100% premium pure foam memory, washable skin-friendly short plush cover and durable zipper.
