This chair cushion uses high-quality memory foam, which excellently disperses the pressure on your buttocks, providing excellent sitting comfort. It has 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 the sides naturally fit the buttocks, dispersing the pressure on them. [W-shaped design at the front] 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] The unique U-shaped structure avoids weak areas such as the coccyx, improving the drawback of the pressure on the coccyx caused by conventional cushions. It reduces the pressure on the coccyx from a seated position, gently cares for the coccyx, and provides comfortable sitting. 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] It uses memory polyurethane, which firmly supports the body, disperses the pressure on the buttocks, and will never deform even after sitting for long periods. To provide high-quality products, it has undergone European standard testing (RoHS) and cleared safety standards! We deliver excellent products, making them perfect as gifts.

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.
