Akachan Honpo Mama Support Cushion, Gray Price: ¥3,278 (tax included) Purchased at a store in early 2024 for childbirth preparation, but it was not used much after opening, so I am selling it. Excerpt from the Akachan Honpo website: A donut-shaped cushion that supports pregnancy and postpartum. Made with low-rebound material, it gently fits the buttocks. The cushion cover is suitable for all seasons. Also, if it gets dirty, you can remove and wash the cover only. ● Material = 100% polyester ● Size (approx. cm) = 40 x 9 Search terms: Donut cushion Donut cushion Round seat cushion Lower back pain relief
