Operating Instructions

1. Seat 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 slightly and pull the lever up. Release the lever at your desired height to lock it in place.

2. Recline and Tilt-Lock Function

The chair offers multiple reclining positions: 90° (work), 110° (relax), and 135° (sleep). To recline, pull the lever on the left side beneath the seat outwards to unlock the rocking function. Lean back to your desired angle and push the lever inwards to lock the tilt. To adjust tilt tension, rotate the knob located at the front underside of the seat.
