5. Operating Instructions
5.1 Height Adjustment
To adjust the chair's height, pull the lever located on the right side of the seat upwards. While holding the lever:
- To raise the chair: Lift your weight off the seat.
- To lower the chair: Remain seated and apply pressure.
Release the lever once the desired height is reached.
5.2 Backrest Recline
The backrest can be reclined from 90 degrees (upright) to 180 degrees (flat). To recline, pull the lever on the left side of the seat upwards and lean back. Release the lever to lock the backrest in your desired position.

5.3 Rocking Function (Tilt Tension)
The chair features a rocking function. To enable it, pull the height adjustment lever outwards. To disable it and lock the chair in an upright position, push the lever inwards.
The tilt tension can be adjusted by rotating the round knob located underneath the seat. Turn clockwise to increase tension (making it harder to rock) and counter-clockwise to decrease tension (making it easier to rock).
5.4 Swivel and Mobility
The chair offers 360-degree swivel for easy rotation. The smooth-rolling casters allow for effortless movement across various floor surfaces.
6. Maintenance
- Cleaning: For general cleaning, wipe the synthetic leather with a soft, damp cloth. For stubborn stains, use a mild soap solution and wipe dry immediately. Do not use abrasive cleaners, solvents, or harsh chemicals.
- Hardware Check: Periodically check all screws and bolts to ensure they are tight. Re-tighten if necessary to maintain stability and safety.
- Caster Care: Keep the casters free of hair, dust, and debris to ensure smooth rolling. You can remove them periodically to clean the axles.
- Gas Lift: The gas lift is maintenance-free. Do not attempt to disassemble it.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Chair wobbles or is unstable | Loose screws; uneven floor | Check and tighten all assembly screws. Ensure the chair is on a flat surface. |
| Chair does not adjust height | Gas lift not engaged; faulty gas lift | Ensure the height adjustment lever is fully pulled. If problem persists, contact customer support. |
| Backrest does not recline or lock | Recline lever not engaged; mechanism issue | Ensure the recline lever is fully pulled/released. Check for obstructions. |
| Casters not rolling smoothly | Debris in casters; damaged casters | Clean casters of hair and debris. Replace if damaged. |
