First, ensure that the screws connecting the armrest are tightened sufficiently. If the issue persists, check the stability of the armrest pad itself.

Adjust the chair to its maximum height using the lever. If it is still not suitable, the gas lift may need to be replaced. Contact support for assistance.
Check if all parts and screws are installed tightly. If the noise continues, there might be an issue with the mechanism. Recording a video of the issue can help support diagnose it.
It is recommended to leave the chair in a well-ventilated room for 2-3 days before use to allow any new-material odors to dissipate.
