How to Fix an Office Chair That Won’t Stay Up: A Comprehensive Guide
Read our comprehensive guide on How to Fix an Office Chair That Won’t Stay Up and find easy solutions to the problem.
How the mechanism of an office chair works
Understanding the mechanism of an office chair is crucial for fixing issues. A chair with height adjustment operates on a pneumatic cylinder, utilizing compressed air pressure.
The height adjustment valve, a key component, regulates seat height. When standing up with no load on the seat, the valve opens, allowing air to move upward, raising the seat.
Conversely, if there’s a load when the valve opens, air moves downward, causing the chair to lower. Familiarizing yourself with this principle enables effective troubleshooting and repairs.

Why won’t my office chair stay up?
Understanding why your chair keeps lowering is crucial for effective repairs. The most common cause is pressure weakening inside the piston mechanism, often due to nitrogen leakage.
Over time, this may happen due to excessive load, abrupt seating, or natural wear and tear on machine parts. The maximum allowable load is typically around 300 pounds.
Fixing a broken cylinder at home is not feasible, as it involves factory-filled compressed gas. The practical options are to replace the cylinder or set the chair at a fixed height, with the former being the preferred solution.
How to solve the problem
It’s crucial to note that attempting a DIY repair on a broken chair cylinder is not feasible. The cylinder, filled with compressed gas (nitrogen) during manufacturing, cannot be refilled at home.
You can replace the cylinder or secure the chair at a fixed height as a practical solution. Generally, replacing the cylinder is the preferred and more effective option.

Replace the office chair gas lift
Opting to replace the office chair gas lift is the most effective solution to resolve the issue of a sinking chair fully. Follow these steps for a successful cylinder replacement:
Preliminary Preparation:
- Begin by flipping the chair upside down after removing the armrests. This makes the process more accessible.
Disassembly:
- Use a screwdriver to detach the seat from the piston system. Carefully remove the gas cartridge body.
Installation of a New Gas Lift:
- Secure the new gas lift in place using screws and a screwdriver. Reattach the seat and test the piston system by raising and lowering the chair. Smooth movements indicate a successful replacement.

If you prefer a more straightforward fix that maintains the chair at a fixed height, consider installing a Saver Kit. This kit ensures the chair stays at your desired height by adding spacers to support the seat.
Attach enough rings onto the piston to maintain the desired height. The spacers bear the body’s weight, offering comfort. Additionally, keep spare rings on hand for easy replacement if needed.
Using a Hose Clamp to Fix a Sinking Office Chair
If your office chair won’t stay up, here’s a simple method using a hose clamp. Follow these steps:
Remove Plastic Cover:
- Take off the visible plastic cover over the metal cylinder. This exposes the metal tube necessary for fixing the hose clamp.
Adjust Chair Height:
- Set the chair to your desired height, as adjusting it later might be challenging. For optimal comfort, the chair should align with your knees when standing.
Attach Hose Clamp:
- Purchase a hose clamp from a hardware store. After obtaining it, pull the end with a belt and wrap the clamp around the metal cylinder. To enhance grip, wrap a strip of duct tape around the clamp; it must be tight to support the chair.
Tighten the Hose Clamp:
- Confirm the chair is at the correct height, then tighten the hose clamp. Slide it up on the metal cylinder, grasp the top, and rotate the screw to secure it in place.
Test Your Chair:
- Test the chair to verify the hose clamp’s effectiveness. It should prevent the chair from sliding down and maintain the desired height. If necessary, make further adjustments by moving the clamp higher or lower.
If this method doesn’t resolve the issue and your chair still won’t stay up, alternative solutions exist.

Using PVC Pipe to Prevent Office Chair Sinking
If you’re dealing with a sinking office chair, consider using a PVC pipe for added support. Follow these steps for an effective solution:
Measure Chair’s Cylinder:
Remove the plastic cover from the chair’s metal cylinder and use a ruler to estimate its diameter. Exact measurement is not crucial, but you can work it out if desired.
Purchase PVC Pipe:
Procure a PVC pipe with a diameter similar to the chair’s cylinder. Ensure it is long enough to cover the entire length of the chair, from the wheelbase to the seat.

Fit the PVC Pipe:
Two installation options are available. You can either saw the PVC pipe lengthwise to create a slit for snapping onto the chair cylinder, remembering to wear a mask during cutting. Alternatively, remove the chair base and slide the pipe onto the cylinder.
Adjust Height:
To increase the chair’s height, raise it and add more PVC pipe. This prevents the chair from lowering and addresses the issue.
Test Your Chair:
Test the chair to verify the PVC pipe’s effectiveness. It should act similarly to a hose clamp, preventing the chair from lowering to an uncomfortable height.
If the problem persists, investing in a new office chair from Furniture At Work might be a worthwhile consideration, given their fantastic range suitable for various professional environments.
Preventing Office Chair Sinking:
If you’ve faced the need to replace your office chair’s gas lift, consider these tips to prolong the piston’s life:
- Adjust the load on the chair within allowable limits.
- Enter and exit the chair smoothly to avoid stress on the gas lift.
Minimize frequent changes in seat height; find an optimal position when possible.
Following these guidelines doesn’t guarantee decades of chair life but can extend its durability. Now you’re familiar with How to fix an office chair that won’t stay up.
