How to Fix a Sinking Desk Chair

Desk chairs use a pneumatic cylinder for the height adjustment system. The cylinder uses pressure. The pressure tends to get lost over time, and the system fails. When it does, the chair cannot hold at a high height. Below are some steps to follow and fix such a challenge.

  • Slide the plastic covering off the cylinder. Most chairs have a plastic covering over the cylinder. Push it up until you can see the metallic cylinder.
  • Note that since the pressure is lost, you will not be able to adjust the height of the chair like before. You, therefore, need to set it at the most convenient height.
  • If the plastic covering is still over the cylinder at you preferred height, you need to get rid of it. To remove it, turn the chair up-side-down, push the retaining clip at the bottom of the chair with a screwdriver, then pull off the wheels. Remove the covering and put the wheels back on.
  • Take a 2cm hose clamp and wrap it around the metal part of the cylinder, but do not tighten it.
  • You will need to reinforce the hose clamp with a strip of rubber or duct tape to ensure it is strong enough to hold the chair up.
  • Now tighten the clamp as far as it can go. The chair should not be able to go below that point. Test the chair and double check whether the hose clamp is holding on tight.
  • You could also use a PVC pipe instead of the wrap clamp. You should get a very strong PVC pipe. Measure the distance of the exposed metal cylinder between the upper covering and the lower end. Cut a pipe of that measure, remove the wheels and insert the pipe, put the wheels back on. You should set the chair at your preferred height while taking the measurements.
