Replacing the gas lift
Replacing a gas lift is usually quite simple. Read here how to replace the gas lift of your office chair yourself.
In many cases, the old gas lift is firmly stuck in the base and the mechanism of the chair. With a removal tool, you can loosen the gas lift more easily. This allows you to replace the gas spring faster and without unnecessary damage to the chair parts.
