Why Remove Gas Lift from Office Chair?

“I am not comfortable in my office chair. I don’t feel good while sitting on my chair. Then I try to find out the reason. And I can notice that it is sinking. Even I cannot adjust my chair up and down correctly.”

This is a common complaint about office chairs. Most of the time, we can see that the seats of the office chairs sink after using them for a few years. This is because the gas cylinder of the office chair is not working well.

A gas lift cylinder or the gas chamber is considered the heart of an office chair. You feel any discomfort sitting in your office chair or face problems in moving or getting up and down. In this case, you must remove the gas lift from the office chair.

Task of Gas Lift Cylinder in Office Chair

As we already said, that gas lift cylinder is considered as the heart of the office chair. As you know that you can move sitting in office chairs. Again, you can adjust the height of the office chair as you need. The gas lift cylinder is the part that helps to do so.

There are two types of gas cylinders used in office chairs. These are:

  1. Pneumatic Cylinders
  2. Hydraulic Cylinders

The work of both types of chairs is quite similar. The main difference between these types is in their chamber. The pneumatic cylinder has one chamber, while the hydraulic has two air chambers.

The main task of the gas lift cylinder is to reserve air inside it. With the help of the compressed air inside it, the chair maintains the height. You can say it helps the chair to stick to the same height.

When you need to lower the height, some of the air releases from the cylinder, thus, the chair seat becomes lower.

Removing Gas Lift from Office Chair

However, now let’s get into the main topic, “How to Remove Gas Lift from Office Chair?” There are many ways to follow to remove the gas lift from the office chair. Here we will describe the easy methods to do the task.

Method-1:

Necessary Tools

In this method, you will need the following tools:

  • Rubber mallet
  • Pipe wrench or a screwdriver
  • A new chair cylinder

NOTE: Before starting work, select a space where you can perform the total procedure freely and safely. Use some soft material on the floor or place to work because it may cause scratches and other damage.

Steps to Follow

Step-1:

Firstly, you have to turn your chair upside down to get a better angle with your wrench. It would be best to raise it to the highest height as though you have access to all parts of the chair.

Step-2:

Secondly, if you have a wrench, secure the wrench near the top of the old cylinder tightly and start twisting it until it releases from the mechanism.

When you don’t have any pipe wrench, you can unscrew the main bolts to remove the chair’s mechanism.

Step-3:

Now, remove the seat from the chair using the rubber mallet. You will find the gas lift is fixed at the top and bottom of the chair with a friction taper lock.

Step-4:

In this step, you can apply for a release agent, both the gas lift meeting points of the 5-star base and the seat base to your chair. Then with your rubber mallet, tap the underside and away from the chair.

Step-5:

Hold the 5-star base. This time you should support the weight of the chair. Fix the chair in the right position, and also root it firmly. If it moves, you cannot do the work properly.

Sometimes the gas lift may not stand out from the center of the 5-star base. That time you may drift and take help from someone to hold the 5-star ground tightly while replacing.

Step-6:

Now you can start hitting the base of the gas lift with the hammer or rubber mallet. But if you see that the mechanism seems stuck, it would be better to apply some heat before tapping it with your rubber mallet.

At this point, it would be ideally best to hit close to the gas lift piston. After a few moments, you will see that the gas lift gets separated from the 5-star base. But be careful while hitting as though not to damage the chair. Remember, the fit could be very tight for use over a long period. That time you may have to hit more to release.

Step-7:

If your chair has plastic covers in the gas lift and seat unit’s meeting point, remove any covers by unscrewing. Your task will be finished in this step. You will get the gas lift removed from the chair.

Method-2:

Necessary Tools

In this method, you will need the following tools:

  • Hammer
  • Releasing Agent
  • Screwdriver
  • WD40

NOTE: Before starting work, select a space where you can perform the total procedure freely and safely. Use some soft material on the floor or place to work because it may cause scratches and other damage.

Steps to Follow

Step-1:

Firstly, you have to turn your chair upside down to get a better angle with your wrench. It would be best to raise it to the highest height as though you have access to all parts of the chair.

Step-2:

Secondly, fix the chair position as the chair doesn’t move around while working.

Step-3:

Now you have to separate the castor from the chair. Apply some WD40 on the rusted area between the chair and the castor. Leave it for a few minutes, and then it will be separated easily. You have to detach the wheelbase.

Step-4:

Finally, it is time to detach the gas lift from the castor. You need to apply some force carefully thus the gas lift doesn’t get damaged. If you find it hard to detach, try once again with more energy.

Other Way:

If you find this process difficult to remove the gas lift, you can try to do it with a hammer. You have to remove the wheelbase according to the described steps. Then take the hammer and hit on the bottom of the chair cylinder.

You will get the cylinder released. Now remove the gas lift from the cylinder. This is all to remove the gas lift from the office chair.
