Size: 38cm x 45cm Color: Black [Recommended chair pad for those who sit for long periods] Sitting for long hours can put a significant strain on your lower back and other areas. This chair cushion uses high-quality memory foam, which excellently disperses the pressure on your buttocks, providing excellent sitting comfort. The three-dimensional structure that wraps and supports your buttocks makes 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 concavity 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 conforms to 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 tailbone, improving the shortcomings 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 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] Using memory polyurethane, it firmly supports the body, disperses the pressure on the buttocks, and will never deform even after sitting for long hours.
