Reference price online: 3900 yen Top Highlights Brand: Gadeel Features: Sex, Breathability Size: Cushion Material: Memory foam Shape: Round Target age: Adults [New Type Cushion - For a Beautiful Silhouette] The new cushion is designed based on a natural physiological arc, constantly maintaining the S-curve of the spine. Adopting a unique design, it naturally shifts the body's center of gravity backward when sitting. The spine is naturally straight, promoting proper alignment. The cushion naturally indents, fitting the buttocks firmly and protecting the natural curve. Just by sitting, you maintain a posture that naturally leans forward, and your back muscles naturally stretch, so if you use it for a long time, your buttocks will lift more, and you will become more beautiful. (※Note: This product only plays a role in assisting the correct sitting posture, and cannot correct sitting posture.) [Excellent breathability, prevents stuffiness] The cover surface uses double mesh fabric, and the synergistic effect of the hollow design of the inner material and ventilation holes reduces the feeling of close contact with the body, and is highly breathable, so you can use it cool and comfortably even in summer without the discomfort of body temperature accumulating in the cushion. Since moisture does not easily accumulate, mold is also less likely to grow, so you don't have to worry. [Three-dimensional structure that wraps and supports the buttocks] The arc-shaped sides gently fit the buttocks and distribute the pressure on the buttocks. The W-shaped linear design at the front end gently fits the thighs, reducing pressure on the thighs and allowing you to sit comfortably. [Highly breathable mesh fabric & non-slip processing on the back] The cover is made of mesh fabric, which is not stuffy. The cover has a zipper, so you can remove the cover and wash it, making it easy to care for. The back is non-slip, so you don't have to worry about the cushion falling from the chair, etc.
