Operating Instructions
Your Yaheetech Boucle Desk Chair offers several adjustable features for personalized comfort.
Height Adjustment

Tilt Function
The chair features a rocking function for added comfort. Pull the same lever (used for height adjustment) outwards to activate the tilt, allowing the chair to rock. Push the lever inwards to lock the chair in an upright position. The tilt tension can be increased or decreased by rotating the round knob located at the front underside of the seat.

Troubleshooting
If you encounter any issues with your Yaheetech Boucle Desk Chair, please refer to the following common troubleshooting tips:
- Chair does not adjust height: Ensure the pneumatic cylinder is correctly installed and the height adjustment lever is fully engaged. Sometimes, sitting firmly on the chair while pulling the lever can help.
- Chair does not roll smoothly: Check the casters for any hair, debris, or obstructions that might be preventing smooth movement. Ensure all casters are securely inserted into the chair base.
- Chair feels unstable or wobbly: Verify that all screws used during assembly are tightened securely. Check the connections between the chair base, pneumatic cylinder, and seat mechanism.
- Backrest does not tilt: Ensure the tilt lock lever is disengaged (pulled outwards). Adjust the tilt tension knob to a looser setting if the tilt feels too stiff.
