◆◆Thank you for viewing◆◆ This is a hip-shaped cushion with a hole, designed with a three-dimensional shape to correct sitting posture. It distributes body pressure and alleviates pain in the buttocks caused by sitting in the same position for long periods. I used it for about six months, and then stored it at home. Please understand that this is a used item. It may be folded for shipping. Thank you for your understanding.
