5. Operating Instructions and Adjustments
Your Flysky Mesh Office Chair offers several adjustable features to enhance your comfort and support.
5.1. Height Adjustment
To adjust the seat height, locate the lever on the right side beneath the seat. While seated, pull the lever up to lower the seat. To raise the seat, stand up and pull the lever up. Release the lever at your desired height.
5.2. Tilt and Recline Function
The chair features a tilt lock function and a recline range of 90-135 degrees. Use the lever on the left side beneath the seat to lock or unlock the tilt mechanism. To adjust the recline tension, turn the round knob located at the front underside of the seat. Turn clockwise to increase tension (making it harder to recline) and counter-clockwise to decrease tension (making it easier to recline).

5.3. Flip-Up Armrests
The upholstered armrests can be flipped up to allow the chair to be stored closer to your desk, saving space. Simply lift the armrests upwards until they lock into the vertical position. To return them to the down position, gently pull them down.
