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 the desired height to lock it in place.

5.2. Armrest Adjustment (Flip-up Function)

The armrests are designed to flip up 90 degrees. To raise an armrest, simply lift it upwards until it locks into the vertical position. To lower it, pull it down. This feature allows the chair to be stored under a desk, saving space.

5.3. Tilt/Rocking Function

The chair features a 120-degree tilt tension and rocking function. Locate the lever on the left side beneath the seat.

• Engage/Disengage Rocking: Pull the lever outwards to enable the rocking function. Push it inwards to lock the backrest in an upright position.
• Adjust Tilt Tension: The round knob located at the front center beneath the seat controls the tilt tension. Turn clockwise to tighten the tension (making it harder to recline) and counter-clockwise to loosen it (making it easier to recline).
