Examine to see if the chair’s gas lift is still working properly. The gas lift is what allows you to adjust the height of the chair. The gas lift can become worn out, causing the chair to slowly sink.

Why do office chairs sinking?

why we need

There is actually a very simple reason why this happens.

The office chair cylinder has lost its lift. 

An office chair cylinder is the part of the chair that connects the base to the seat.

And it is what allows us to adjust the chair up and down.

Inside the chair, the cylinder is Nitrogen gas.

So when you pull the chair lever, the nitrogen gas is switching chambers inside the cylinder, allowing it to move up and down.

More technical specifics about gas springs can be found here.

Long time and after excessive use of your chair, the seal around the nitrogen gas can weaken, causing it to slowly leak out.

When this happens, you’ll start to notice your office chair slowly sinking lower and lower to the ground.

The good news is that this problem is easily fixed!

All you need is a can of compressed air. Simply point the nozzle of the compressed air at the valve on your office chair cylinder and give it a few blasts.

This will release more nitrogen gas into the cylinder, restoring its lift and returning your chair to its original height!
