I used this to help with the pain from an episiotomy after giving birth! I couldn't sit without it, and this cushion really helped me. However, I only used it for about a month after delivery. There are no noticeable scratches or stains other than those in the photos, but please understand that this is a used item. Approximately 40cm in diameter and 8cm thick.
