Round Seat Cushion Donut Hemorrhoids Postpartum Light Gray High-Density Urethane Low-Rebound Chainavi Diameter 42cm Inner Diameter 11cm Thickness 11cm Tax included: ¥3,080 I developed hemorrhoids after giving birth, so I purchased various round seat cushions in October 2025. However, I found another one I preferred, so I am selling this one. (Note) Although it is described as high-density urethane low-rebound, it feels high-rebound due to the high density. I sat on it once to try it out, but if you are still interested, please purchase it!
