This chair cushion uses high-quality memory foam and a three-dimensional structure that wraps and supports your buttocks, making it a memory foam cushion that allows you to sit comfortably for long periods. 【Three-dimensional design that wraps and supports the buttocks】The slight indentation and sides naturally fit the buttocks, distributing the pressure on the buttocks. 【W-shaped design at the front】Both sides absorb the pressure from the buttocks 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 weaker areas such as the tailbone, improving the drawbacks of conventional cushions that compress the coccyx. It reduces the pressure on the tailbone from a seated position, gently cares for the tailbone, 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. 【Memory Foam Material & High-Quality Product】Using memory polyurethane, it 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. 【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.) 38cm long x 45cm wide x 4-11cm thick Material: Core: Polyurethane (high-quality memory foam) Cover: Surface/100% polyester (breathable mesh material) Back: PVC material (with non-slip and anti-adhesive particles). Please note: If you are using a memory foam cushion for the first time, it may take 1-2 weeks to get used to the feel of the memory foam material. ■ Condition Stored at home and opened for photography and inspection. *This item has been in someone's hands once, so please refrain from purchasing if you are sensitive to this.
