1. Find the problem

Do you have an office chair that seems to be slowly sinking? This can be a problem because it can cause discomfort and even back pain. The good news is that there are a few things you can do to fix a sinking office chair.

First, you need to find the problem. If the chair is sinking because of a broken hydraulic mechanism, then you will need to replace the part. If the chair is sinking because of worn out casters, then you will need to replace the casters.

You may also need to adjust the tension on the springs. Once you have found the problem, it should be easy to fix your sinking office chair.

2. Identify the cause of the problem

In most cases, a sinking office chair is caused by a broken gas lift. The gas lift is a cylinder that contains gas and is located underneath the seat of the chair. When the gas lift is working properly, it provides height adjustability for the chair. However, over time the gas can leak out, causing the chair to slowly sink.

To fix a sinking office chair, you will need to replace the gas lift. This can be done by unscrewing the old gas lift from the bottom of the chair and screwing in a new one. In some cases, you may also need to replace the seat base or casters.

3. Fix the issue with a solution that works for you

A sinking office chair can be a real pain-literally. If your chair isn’t adjusted properly, you may find yourself constantly slouching or hunching over your desk. This can lead to neck and back pain, as well as headaches.

The good news is that there are a few easy ways to fix a sinking office chair. First, check the tension knob underneath the seat. If it’s turned all the way to the “loose” position, tighten it until the seat is at the desired height. If that doesn’t work, try removing the gas cylinder from the base of the chair.

Once it’s removed, take a look at the piston inside. If it’s bent or damaged, it will need to be replaced. Finally, if all else fails, you can always replace the entire chair.

4. Test your fix and make sure it’s holding up

Once you’ve fixed your sinking office chair, it’s important to test your repair to make sure it’s holding up. Sit in the chair and wiggle around a bit to see if the issue has been resolved. If the chair feels sturdy and doesn’t sink down, then your fix is successful! If the chair is still sinking, you may need to try another repair method.

But don’t despair – with a little trial and error, you’ll be able to fix that pesky office chair in no time.

How can I prevent my office chair from sinking?

Over time, office chairs can start to sink, making it difficult to remain comfortable and productive at work. There are a few simple things you can do to prevent your chair from sinking.

Finally, avoid sitting in the same position for extended periods of time. Taking occasional breaks to stretch and move around will help to keep your body from sinking into the chair.


Sinking office chairs are a real problem for many people. They can lead to back pain, discomfort, and neck aches. By following the tips we outlined above, you can fix your sinking office chair and get back to being productive at work.
