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. Size: Width 44cm, Length 41cm, Height 18cm [Exterior fabric composition] Surface and sides: 100% polyester (antibacterial treatment) Back: 65% polyester, 35% polyurethane (anti-slip treatment) [Filling] Urethane foam Country of Origin: China "Keeps" is a support cushion that helps you maintain a comfortable posture just by placing it on your usual chair. It gently supports your bottom and helps you maintain a comfortable posture even when sitting for long periods of time. The chair at home or in the office is hard and you can't concentrate, and your waist and back hurt when you sit. This product naturally supports the sitting posture of such people. It is made of rich urethane material with high elasticity and excellent body pressure dispersion, so it is not too hard and not too soft, but wraps around your buttocks, and you can continue to sit comfortably for a long time. It can be easily used by simply placing it on your usual chair, such as during long hours of desk work or hobby time. Correct posture is when your ears, shoulders, and hips are in a straight line. The ischial pocket is designed to position your pelvis for ideal posture. By sitting so that your ischial bones fit into the ischial pocket, your posture will not collapse forward, and the sacrum point will be supported, leading to an ideal sitting posture. The design makes it easy to maintain correct posture just by sitting. When sitting without a cushion, about 85% of the pressure is concentrated on the sit bones. When using the Keeps cushion, the pressure on the sit bones is reduced by about 30%. Body pressure is distributed over the entire contact area with the cushion, allowing you to sit comfortably for long periods of time. Keeps is an application of Nishikawa's ideas. Using the same body pressure measuring device used to make pillows, we researched the pressure on the buttocks when sitting, and pursued comfort when sitting. It is designed to distribute pressure concentrated on the ischial bones while maintaining a good posture. Air holes are placed in the urethane foam around the thighs, which are in contact with the ground when sitting, to allow air to pass through, preventing stuffiness even when sitting for long periods of time. The back of the cushion is treated with an anti-slip coating. This reduces the stress of the cushion slipping off the chair!
