If the gas lift no longer holds your weight, or it doesn’t function as it should anymore, you will need to remove and change the gas lift from your office chair. Join FittingChairs to see how to remove gas lift from office chair.
Test your gas lift
Before coming to the part of how to remove gas lift from office chair, you need to test your gas lift first.
If your gas cylinder sinks all the way to the bottom when you sit, try to adjust your lever. It may because the lever is too tight that it presses on the lock even when you are not touching it.
If that is not the case, try to tighten the screws on your gas cylinder. Loose screws will not allow enough pressure to stay inside the cylinder.
If the problem is that the cylinder won’t sink down when you press the lever, check if the lever is working properly. You should also check the lock on your cylinder head to make sure it’s functioning.
If you’re still experiencing problems after testing your gas cylinder, maybe it’s time for you to remove and replace it.

How to remove gas lift from office chair?
Follow these steps of how to remove gas cylinder from office chair when you need to:
You’ll need an adjustable wrench to remove the four bolts, a screwdriver to remove additional locks, and a rubber mallet.

Step 2: Unscrew the four bolts that connect the top of the chair to the mechanism under it.
You can turn the chair upside down to get a better angle with your wrench. Make sure you do this on a smooth surface in order not to scratch up your chair’s cushions.
Once all four bolts are unscrewed, take the top part of the chair and set it aside.
Step 3: Remove the base of the chair from the cylinder.
Take the cylinder with one hand and hold it upright. Gently tap the base downward with your rubber mallet using your other hand. Go around the entire base, tapping it as close to the cylinder as possible.
When the base comes off, proceed to remove the mechanism from the cylinder.
Step 4: Remove the mechanism from the cylinder.
Take the cylinder with one hand and hold it upside down this time. Then, using your free hand, gently tap the mechanism downward with your rubber mallet.
Removing the mechanism from the cylinder is more difficult than removing the base. If the mechanism seems stuck, try to apply some heat before continuing to tap it with your rubber mallet.
If you’re still having trouble removing the mechanism, use a removal tool that usually comes with replacement gas cylinders.
How to replace the gas lift?
Now you know how to disassemble office chair gas cylinder. Let’s move on to how to replace the gas lift.
How to choose the right gas lift for office chair?
It’s not hard to find a replacement gas lift for your office chair, as most office chairs today use the same standard gas cylinder.
However, to be sure that you buy a right one, it’s a good idea to take some measurements first.
There are three important measurements you need to make to ensure that you get the correct replacement gas cylinder:
- Gas spring diameter
The gas spring is the top portion of your cylinder. At the tip of this spring is where your release button is located.
The standard measurement of a gas spring is 1.1 inches in diameter.
- Column diameter
The column is the bottom part of your gas cylinder. This usually slightly protrudes from the bottom of your chair base. The standard measurement for the column is 2 inches in diameter.
If yours has a different size, don’t worry! You’re still going to find one that will fit your office chair.
- Gas cylinder stroke
Your gas cylinder stroke is the distance your chair can move from its lowest position to its highest position. A 4-inch stroke gas cylinder means that your chair can be adjusted 4 inches up from its lowest position.

Install replacement gas lift
Once you get a hold of your new replacement gas cylinder, the next step will be to install it. Let’s take a look at the steps to install your replacement gas cylinder.
Step 1: Preparation
Carefully remove all protective wrappings so they don’t get stuck when you put your chair back together.
It’s a chance to clean the mechanism and base sockets on your office chair. Remove any dirt that might cause trouble when you try inserting the new gas cylinder.
Step 2: Install the gas lift cylinder
Insert the gas spring into the socket on your office chair mechanism. Give it a firm push to secure it in place.
Then, insert the other end into the socket on your wheelbase. Give it a few taps with your rubber mallet until it’s nice and tight.
If your gas cylinder comes with washers or bearings, install these with your gas cylinder.
If your gas cylinder has a pin at the bottom of the column, fasten the pin using a screwdriver.
Step 3: Reassemble your office chair
After installing your new gas cylinder, put all the other pieces of your office chair back together.
You can start with the casters. Firmly push each caster into the five caster sockets on your wheelbase.
When the casters are installed, align the holes on your seat with the four bolt holes on your mechanism. Insert the bolts one by one and tighten them using a wrench.
