[Ergonomic U-Shaped Design | Reduces Strain on Waist and Coccyx] Our unique U-shaped cutout effectively distributes pressure on the coccyx, reducing fatigue. The three-dimensional structure on both sides provides firm support for the lower back, guiding you to a correct posture that is comfortable even for long periods. The ergonomic molded foam fits the body's contours for a comfortable seating experience.
[High-Density Memory Foam | Comfortable Even for Long Sitting Periods] Made with approximately 10cm thick high-density memory foam that resists deformation and provides firm support. The foam is infused with bamboo charcoal for both cleanliness and breathability, ensuring a comfortable seat. The soft feel gently cradles your body, making it ideal for long hours of desk work. *Recommended for individuals weighing 90kg or less.
[Design Guides You to a Natural, Correct Posture] The gentle forward tilt design naturally shifts your center of gravity forward as you sit. This straightens your back and naturally leads to a proper posture without strain. It's easy to maintain balance even when sitting for long periods, reducing strain on your lower back.
[Washable Cover & Non-Slip Finish for Always Cleanliness] The cover is removable and washable. Made with top-class materials in the industry, it offers excellent breathability and is resistant to pilling, ensuring a durable and reliable cushion. The non-slip finish on the underside provides excellent stability and prevents shifting. It also features a convenient handle for easy portability, making it useful at the office or on the go. *The core material (memory foam) is not washable.
