A plain perforated cushion that can be used on chairs or in the living room. It reduces the burden on your buttocks and lower back, making it ideal for those who have trouble with their buttocks. If you are concerned about dirt, you can wash it by hand, so it is easy to clean and can be used cleanly at any time. Because it is filled with cotton in Japan, it has just the right amount of cushioning. This environmentally friendly cushion uses polyester fiber made from recycled plastic bottles for the warp.
