[0002] A chair back mesh pad refers to a soft cushion placed on the back of a chair. It can provide extra comfort and support, and can provide people with a more comfortable and pleasant sitting experience. Compared with other styles of cushions, the mesh style of the chair back mesh pad is not only beautiful and elastic, but also has good breathability.

[0003] The existing chair back mesh pad cannot adjust its temperature during use, resulting in that when the chair back mesh pad is used in the cold winter, the body parts that come into contact with the chair back mesh pad cannot maintain a suitable temperature due to the mesh holes on the surface of the chair back mesh pad. At the same time, the existing chair back mesh pad cannot adjust its thickness, and the chair back mesh pad cannot be adjusted with each user, so the user's back cannot fit the chair back mesh pad, causing airflow to pass through the user's back and the chair back mesh pad, thereby causing the temperature to drop, affecting the user's experience.
