【Online Price】 ¥5,780 【Color】 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 memory foam, which excellently disperses pressure on your buttocks, providing exceptional comfort. Its three-dimensional structure supports and cradles your buttocks, making it a low-rebound cushion that allows you to sit comfortably for extended periods. 【Three-Dimensional Design that Supports and Cradles Your Buttocks】The slight concavity and the sides naturally fit your buttocks, distributing pressure. 【W-shaped design at the front】Both sides effectively absorb pressure from the buttocks. It naturally conforms to your buttocks, gently cradling them for a perfect fit. 【U-shaped design at the rear】The unique U-shaped structure avoids sensitive areas like the tailbone, improving upon the shortcomings of conventional cushions that can cause tailbone compression. It reduces pressure on the tailbone from a seated position, gently caring for the tailbone and providing comfortable seating. Furthermore, this unique design improves the cushion's breathability, preventing stuffiness even when sitting for long periods. 【Memory Foam Material & High-Quality Product】Made with memory polyurethane, it firmly supports the body, disperses pressure on the buttocks, and will not 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. 【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, allowing you to 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 slipping off the chair. 【Product Specifications】Size: (approx.)
