This chair cushion uses high-quality memory foam, which distributes the pressure on your buttocks, providing excellent comfort. The three-dimensional structure that wraps and supports your buttocks is a memory foam cushion that allows you to sit comfortably for long periods. [Three-dimensional design that wraps and supports your buttocks] The slight indentation and the sides naturally fit your buttocks, distributing the pressure on your buttocks. [W-shaped design at the front] Both sides absorb the pressure on your buttocks well. It naturally fits your buttocks and gently wraps them, providing excellent fit. [U-shaped design at the rear] The unique U-shaped structure avoids weak areas such as the tailbone, improving the shortcomings of conventional cushions that put pressure on the coccyx. It reduces the pressure on the tailbone from a sitting position and gently cares for the tailbone, providing 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. [Memory foam material & high-quality product] Made of memory polyurethane, it firmly supports the body, distributes the pressure on the buttocks, and will never deform even after sitting for long periods. [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.
