Operating Instructions
Height Adjustment
To adjust the chair's height, locate the lever under the seat on the right side. While seated, pull the lever up to lower the chair. To raise the chair, stand up slightly and pull the lever up. Release the lever at your desired height.
5-Level Adjustable Armrests
The armrests can be adjusted to five different positions, including a flat position, to accommodate various sitting styles or to create space for pets. To adjust, press the button or lever located on the side of each armrest and move it to the desired angle. Ensure both armrests are set symmetrically for balanced support.

Swivel Function
The chair features a full 360-degree swivel function, allowing for easy movement and access to different areas of your workspace without needing to reposition the entire chair.
Tilt/Rocking Function
To activate the rocking function, pull out the lever located under the seat (usually the same lever for height adjustment). Push the lever in to lock the chair in an upright position. The resistance of the tilt can be adjusted by turning the tension knob located at the front underside of the seat mechanism.
Versatile Seating Positions
The wide seat design allows for comfortable cross-legged sitting, lounging, or traditional upright office posture. Adjust the armrests as needed to optimize your comfort for each position.


Maintenance
Cleaning
The chair is upholstered with premium PU leather, which is waterproof and wear-resistant. For general cleaning, simply wipe the surface with a clean, damp cloth. Avoid using harsh chemicals or abrasive cleaners, as these may damage the material. For spills, wipe immediately to prevent staining.
General Care
- Regularly check all bolts and screws to ensure they are tight. Retighten if necessary.
- Avoid exposing the chair to direct sunlight for prolonged periods to prevent fading and material degradation.
- Keep sharp objects away from the PU leather to prevent scratches.
Troubleshooting
Chair Does Not Tilt or Recline
If the tilt function is not working, ensure the tilt lock lever (usually the same as the height adjustment lever) is pulled out to enable rocking. Also, check the tension knob located under the seat; if it's tightened too much, it may restrict tilting. Loosen the knob by turning it counter-clockwise.
Armrests Feel Loose
If the adjustable armrests feel loose, check the screws securing them to the chair frame. Tighten any loose screws. If the issue persists, ensure the armrest adjustment mechanism is fully engaged in one of its five positions.
Lack of Back Support
While the chair is designed for comfort and versatility, individual preferences for back support vary. If you require additional lumbar support, consider using a supplementary lumbar pillow. Ensure you are sitting correctly with your back against the backrest.
