In addition to the common height adjustment, fore and aft adjustment and backrest angle adjustment, some advanced seat adjustment mechanisms also have the lumbar support adjustment function. Lumbar support adjustment can adjust the position and strength of the lumbar support device according to the user's waist curve and sitting habits, providing a more fitting and stable support for the waist. For people who sit for long periods of time working or driving, this can significantly reduce fatigue and discomfort in the waist.

Adjusting the backrest angle is another important function of the seat adjustment mechanism. By adjusting the tilt angle of the backrest, users can find the most suitable sitting position for themselves, providing sufficient support for their back and neck. This helps to alleviate discomfort caused by prolonged sitting and improve work and driving comfort.
