[0002] The user's sitting support in special simple houses such as sauna rooms, far infrared treatment rooms, and spectrum rooms is often hard and not ergonomically designed, which does not allow people to have a more comfortable experience. In addition, the existing backrests have the following disadvantages:

[0003] 1. The temperature in sauna rooms, far-infrared treatment rooms, and spectrum rooms is relatively high. Most existing backrests are made of sponge or cloth, which are not suitable for high temperature and high humidity environments such as sauna rooms, far-infrared treatment rooms, and spectrum rooms;

[0004] 2. The backrest has poor air permeability, which blocks heat transfer and affects the sauna or treatment effect;

[0005] 3. There are many installation steps, the process is complicated, and it is difficult to remove and clean;

[0006] For example, Chinese patent CN200820038811.0 specifically discloses an adjustable backrest for sauna room, which is composed of three parts: a backrest frame, a backrest board and a pillow board, wherein the backrest frame and the backrest board are integral components, and the pillow board is separately arranged; the integrally arranged backrest frame and the backrest board are fixedly mounted on the back board above the seat board; the separately arranged pillow board is height-adjustable on the back board; the pillow board is height-adjustable to meet the needs of different users. It can be seen that the backrest structure of the above patent is complex, not easy to clean and replace, and has poor air permeability, which is not conducive to high temperature and high humidity environments such as sauna rooms.
