IKSTAR Chair Pad, Low-Rebound, Chair Cushion, Non-Slip Backing, Breathable, Black 【Recommended Chair Pad for Those Who Sit for Long Hours】Sitting for long periods can put a significant strain on your lower back and other areas. This chair cushion uses high-quality low-rebound material, which excellently disperses pressure on the buttocks, providing excellent sitting comfort. It has a three-dimensional structure that wraps and supports the buttocks, making it a low-rebound cushion that allows you to sit comfortably for long periods. 【Three-Dimensional Design that Wraps and Supports the Buttocks】The slight indentation and the sides naturally fit the buttocks, dispersing pressure. 【W-shaped design at the front】Both sides absorb pressure well. It naturally conforms to the buttocks and gently wraps them, providing an excellent fit. 【U-shaped design at the rear】The unique U-shaped structure avoids the weaker areas such as the tailbone, improving the shortcomings of conventional cushions that compress the tailbone. It reduces pressure on the tailbone from a seated position, gently cares for the tailbone, and provides comfortable seating. 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】Made with low-rebound polyurethane, it firmly supports the body and disperses pressure on the buttocks, and will never deform even after sitting for long hours. To provide high-quality products, we conduct European standard testing (RoHS) and clear safety standards! We deliver excellent products, making them perfect 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 prevents stuffiness. The cover has a zipper, so you can remove 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 off the chair.
