Not only is it easy to cause fatigue, but it will also increase the burden and pressure of the lumbar vertebrae. Generally, only the chair with the back of the chair can not support the waist of the user independently, so that the waist can also be relaxed. Therefore, some operators also have the front end of the chair back. A lumbar cushion is added to enhance the comfort of the waist through the lumbar cushion. However, the conventional lumbar cushion structure is not difficult to find that there are still some shortcomings, mainly due to the chair between the seat cushion and the seat back.
