Memory Foam Chair Cushion Non-slip backing, breathable, black ---Product Description--- Size: 38cm x 45cm [Recommended chair pad for those who sit for long periods] Sitting for long periods puts a lot of strain on your lower back, etc. This chair cushion uses high-quality memory foam, which disperses the pressure on your buttocks, providing excellent comfort. A three-dimensional structure that wraps and supports your buttocks, this memory foam cushion 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, dispersing the pressure on them. [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 an excellent fit.
