This chair cushion uses high-quality memory foam, which excellently disperses the pressure on your buttocks, providing excellent sitting comfort. This low-rebound cushion has a three-dimensional structure that wraps and supports your buttocks, allowing you to sit comfortably for long periods. [Three-dimensional design that wraps and supports the buttocks] The slight concavity fits the buttocks naturally on both sides, dispersing the pressure on the buttocks. [W-shaped design at the front end] Both sides absorb the pressure on the buttocks well. It naturally fits the buttocks and gently wraps them, providing an excellent fit. [U-shaped design at the rear end] The unique U-shaped structure avoids weak areas such as the tailbone, improving the shortcomings of the conventional cushion, which puts pressure on the tailbone. It reduces the pressure on the tailbone from a seated position, gently cares for the tailbone, and provides comfortable sitting. In addition, this unique design improves the breathability of the cushion, making it less stuffy even when sitting for long periods. [Memory foam material & high-quality product] Using memory polyurethane, it firmly supports the body, disperses 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. [Highly breathable mesh fabric & non-slip backing] The cover is made of mesh fabric, which is highly breathable and does not 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.
