This cushion securely wraps your bottom with its ring shape, and is easy to carry. - Size: 44cm diameter - Thickness: 7cm - Weight: 400g - Design: Ring-shaped - Recommended by: Active midwife Thank you for viewing. I purchased this in preparation for childbirth, but I had a C-section and didn't use it, so I am selling it. It is new and unused, and has not been taken out of the bag, but please refrain from purchasing if you are concerned about home storage. It can be folded up small for easy carrying. Original price: ¥3,300.
