Product Description ・【High-density memory foam distributes pressure by receiving body weight over a "surface"】 High-quality, high-density memory foam (low resilience foam) is used. Unlike soft, ordinary foam, it sinks in slowly and fits the shape of your body, dispersing the pressure on your lower back, buttocks, and thighs over a wide area instead of concentrating it on one point. It alleviates the "sharp pain of the ischial tuberosity and coccyx" that could not be resolved with conventional cushions, and provides a "zero compression" seating comfort that makes it less tiring even when sitting for long periods. ・【Three-dimensional molded "support zone" provides specialized care for the lower back and coccyx】 Based on ergonomics, the rear is deeply U-shaped cut, and the front is three-dimensionally W-shaped. This unique shape lifts the coccyx to protect it from direct pressure and wraps the ischial tuberosity to stabilize it. Furthermore, a slight forward tilt naturally raises the pelvis and guides the posture to straighten the back. It provides support to maintain an ideal posture without putting unnecessary force on the body. ・【Temperature-sensing characteristics create the optimal fit with body temperature】 This design takes advantage of the "temperature-sensing" characteristics of memory foam. It supports your posture with moderate firmness at the beginning of sitting, and as the material slowly warms up with your body temperature, the fit increases to match your body shape. The personalized, enveloping feel, like a custom-made product, provides deep relaxation and stability that cannot be obtained with other materials. ・【Breathable & washable cover for lasting cleanliness and comfort】 The surface is made of highly breathable mesh fabric, so it is comfortable even when sitting for long periods without getting stuffy. The cover is washable and can be kept clean. ・【Durable and non-slip stable design that does not lose its shape】 Because it uses high-density material, the support lasts even after long-term use. The bottom is treated with a strong non-slip finish to prevent slipping and rotation on the chair. It maintains a stable position while you are concentrating on work or driving.
