3.1. Height Adjustment

To adjust the chair's height, locate the lever under the seat on the right side. While seated, pull the lever up to lower the chair. To raise the chair, stand up slightly and pull the lever up. Release the lever at your desired height.

3.2. Recline Function and Footrest

The chair features a 135-degree recline function with three tilting positions, allowing you to recline up to 125 degrees for rest or a nap. To recline, pull the recline lever (usually on the left side under the seat) and lean back. Release the lever to lock the position. The integrated retractable footrest can be pulled out from under the seat to elevate your legs, reducing tension and improving circulation.

The chair includes an adjustable lumbar support pad designed to target lower back strain. This support can be moved up and down or adjusted forward and backward to fit the natural curve of your spine. Locate the knob on the backrest to adjust the lumbar support position and depth.
