  • Check the Adjustment Mechanism: If your chair's height lever isn't responding, it could mean there's a problem with the mechanism itself. You might need to replace or fix this part of the chair, but before that, use a bit of lubricant like WD40 to see if it can get things moving again.
  • Inquire into the Gas Cylinder: The unseen hero of any office chair is the gas cylinder, also known as the pneumatic lift. Failing gas cylinders can hinder the chair's ability to raise or lower smoothly. You can learn more about how to fix your chair gas lift on our gas lift chair mechanics guide. You might need to replace the cylinder if it's faulty.
  • Test the Support Structure: The support component of the chair, usually metal or plastic, is crucial for stability and adjustment. Inspect it closely for any signs of wear or damage, and consider replacement if necessary.
