- Shape: U-shaped cushion - Color: Dark blue Used for about 2-3 weeks postpartum. I don't think the cushion is worn out, but it has been used, so please understand that it is a used item. It's a not-too-firm, low-rebound type, and was just right for use after childbirth and on hard chairs. There are no noticeable scratches or stains, but please refrain from purchasing if you are sensitive to items that have been stored at home for a long time. Thank you for looking.
