IKSTAR Chair Pad Used a few times, but no longer needed as I purchased a gaming chair. I hope someone who needs it can use it. ---Product Description--- Size: 38cm x 45cm Recommended for those who sit for long periods. A low-rebound cushion with a three-dimensional structure that supports and envelops the buttocks, allowing you to sit comfortably for long periods. 【Three-dimensional design that supports and envelops the buttocks】Slightly concave, the sides naturally fit the buttocks, distributing pressure on the buttocks. 【W-shaped design at the front】Both sides absorb the pressure on the buttocks well. Naturally conforms to the buttocks and gently envelops them, providing an excellent fit. 【U-shaped design at the rear】The unique U-shaped structure avoids weak areas such as the coccyx, improving the drawbacks of conventional cushions that cause pressure on the coccyx. Reduces pressure on the coccyx from a seated position, gently cares for the coccyx, and provides a comfortable sitting experience. In addition, this unique design improves the breathability of the cushion, making it less likely to get stuffy even when sitting for long periods. 【Low-rebound material & high-quality product】Adopts low-rebound polyurethane, firmly supports the body, distributes the pressure on the buttocks, and will never deform even after sitting for long hours. To provide high-quality products, we conduct European standard inspections (RoHS) and clear safety standards! We deliver excellent products, making them ideal as gifts. (This product test number: IKS-002) 【Highly breathable mesh fabric & non-slip backing】The cover is made of mesh fabric, which is highly breathable and does not easily get stuffy. The cover has a zipper, so you can remove and wash the cover, making it easy to care for. The back is non-slip, so you don't have to worry about the cushion falling off the chair. 【Product Specifications】Size: (approx.) 38 x 45 x 4-11cm Low-rebound Chair Cushion Non-slip backing Breathable Black
