U-shaped donut cushion to alleviate painful discomfort. - Type: U-shaped cushion - Color: Beige - Design: Donut cushion Regular price: ¥5,500 Thank you for viewing. Quoted from the official website below: Developed in collaboration with Dr. Masahiro Nishikawa, an obstetrician and gynecologist, based on feedback from mothers immediately after childbirth, this is a reversible cushion. The softness differs on both sides, allowing you to choose the firmness that suits your preference. Compared to a donut cushion, the U-shape expands the cutout area slightly when seated, reducing contact with painful areas. The side fabric with urethane coating can be easily cleaned by simply wiping away dirt.
