About the headrest
Adjust the seat height by rotating the adjustment lever at the seat base. Sit to lower, stand to raise.
- Pull out the adjustment lever to adjust the seat tilt angle.
- When the backrest is locked at the 130° angle, to unlock the adjustment lever, you must first recline the backrest, and then you can pull out the adjustment lever.
The adjustment lever can only be locked when it is adjusted to the minimum angle of 90° or the maximum angle of 130°.
Hold the armrest height adjustment lever and lift the armrest to adjust its height.
To prevent the headrest from sliding, our headrest has a high resistance. If it's difficult to adjust, please drop a few drops of oil into the slider groove to facilitate adjustment.
