By the Head of an Osteopathic Donut Cushion with Premium Memory for Lower Posture Front High Resilience Donut Meets Safety Standards Regular

Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.

【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary.

【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product.

【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. [Recommended by the Director of an Osteopathic Clinic | Posture Support Donut Cushion] Supervised by the director of an active osteopathic clinic. For long hours of desk work, working from home, postpartum care, hemorrhoids, and back pain. Supports natural posture and reduces strain on the lower back and buttocks. [Made with high-quality 100% premium memory foam] The inside of the cushion uses low-resilience urethane that evenly distributes body pressure. It is not too soft and does not sink too much, and has an exquisite resilience that keeps you comfortable for a long time. [Forward-tilting design makes thighs comfortable] The special structure with a slant on the front reduces pressure on the thighs. It promotes a natural posture with the pelvis upright, making it less tiring even during long periods of concentrated work. [Adjusted to the right firmness | Repeated testing at our own factory] The firmness is adjusted in 5% increments, and after multiple staff members have tried it out, we have found the best balance. This reduces the problems of conventional donut cushions, such as being "too hard" or "resonating with the floor." [Quality tested for peace of mind | Safety for babies] Quality inspections are conducted by specialized institutions on all parts. The highly breathable cover is washable, so you can always use it hygienically. Safe design that can be used by the whole family. [About the smell when opening] Due to the characteristics of the urethane material, you may notice a smell immediately after opening, but it will naturally decrease if you dry it in the shade for about 1-2 days in a well-ventilated place. The smell is not harmful to the human body. [Caution regarding color transfer] Prolonged contact with leather, wood, or resin products may cause color transfer due to the non-slip surface on the underside of the cushion. We recommend using the cushion on a rug or similar surface. [Reliable return policy] Comfort varies from person to person. If you are not satisfied, we accept returns, so please feel free to contact us.
