Filled with high-density memory foam, it is lightweight, soft, and comfortable, and does not easily collapse even after sitting for a long time, providing lasting support. The bottom is designed with raised bumps to ensure that the seat cushion does not slip during use and is compatible with most chairs. Adopting an ergonomic U-shaped design, the hollow structure in the middle effectively reduces pressure on the buttocks, back, sacroiliac joint and other areas, relieving hemorrhoids, pressure sores, prostatitis, pregnancy, postpartum pain and so on. Suitable for various settings including offices, studies, cars, and wheelchairs. | FLAVORA for Pain & Hemorrhoids Relief Memory Foam Ring Donut Cushion in Grey | Size: 125 cm x 180 cm
