I bought this for my delivery in February of this year, but the hospital had a similar cushion, and I didn't have much pain after being discharged, so I ended up hardly using it. This is a donut-shaped cushion made of soft fabric, with non-slip processing. This product is sold on Amazon for 3980 yen. - Color: Beige - Shape: Donut-shaped - Back Material: Non-slip processing - Surface Material: Soft fabric Thank you for looking.
