5.1. Height Adjustment

To adjust the chair height, pull the lever located under the right side of the seat upwards. While pulling the lever, lift your body weight off the seat to raise the chair, or remain seated to lower it. Release the lever to lock the height.

5.2. Backrest Recline

The backrest can be reclined between 90 and 150 degrees. Pull the recline lever (usually on the right side, below the seat) upwards and lean back to your desired angle.
