I purchased this and stored it, hardly using it at all. Pelvic Support Cushion, Brown It wraps around your buttocks 360 degrees and gently catches them with the indentation of the seat. The bottom uses low-resilience urethane, and the fabric is a comfortable-to-the-touch velour, providing a comfortable sitting experience. This donut-shaped low-resilience cushion alleviates the burden on your buttocks and lower back when sitting, making it recommended for hemorrhoids, postpartum care, and long hours of desk work. I will pack it as compressed as possible for shipping. Please purchase with the understanding that this is a used item. Main fabric: Polyester Cushioning material: Urethane foam Product size: Approximately 36 x 33 x 12cm #PelvicSupport #Cushion #RoundCushion #DonutCushion
