Necessary Tools:

To remove the gas cylinder, you will typically need an adjustable wrench, a rubber mallet or a hammer with a rubber end, and a rag or towel for protection.

Workspace Preparation:

Ensure you have a clean workspace with enough room to maneuver around the chair freely.
Consider placing a protective layer on the floor or work surface to prevent any unwanted scratches or damage.

Lowering the Chair to Its Lowest Position

Adjusting the Height:

Ensure the chair is at its maximum lowered position to ease the removal process.
Sit on the chair and push down firmly to lower the seat as much as possible.

Detaching the Chair Base

Locate the Clip or Retaining Ring:

Examine the underside of the chair base where it connects to the gas cylinder.
Look for a retaining clip or ring that secures the gas cylinder to the base.

Removing the Retaining Clip or Ring:

With the rag or towel for protection, grasp the retaining clip or ring firmly with your hand or use pliers if needed.
Carefully and firmly, pull the retaining clip or ring outwards to release it from the base.
Set the clip or ring aside in a safe place as you will need it for reassembly.

Separating the Gas Cylinder from the Chair Base

Lubricating the Connection Point:

Apply a small amount of lubricant or grease to the area where the gas cylinder connects to the chair base.
This will facilitate smooth detachment and make the removal process easier.

Tapping the Gas Cylinder:

Using the rubber mallet or rubber-ended hammer, gently tap the bottom of the gas cylinder.
The purpose is to dislodge any debris or sediment that may cause resistance during removal.

Applying Steady Pressure:

While applying downward pressure on the chair seat, grip the gas cylinder firmly near the top.
Gradually twist and pull the gas cylinder in a steady motion to separate it from the chair base.
Avoid jerking or applying excessive force to prevent damage to the chair or injury.

Safety Considerations:

Exercise caution when removing the gas cylinder to prevent injury to yourself or damage to the chair.
Keep your hands and fingers away from any moving parts during the process.

Inspecting the Cylinder:

Once removed, inspect the gas cylinder for any damage, leaks, or signs of wear.
If any issues are detected, consider replacing the gas cylinder before reassembling the chair.

Reassembly and Replacing the Gas Cylinder

Cleaning the Chair Base:

Before reassembling, clean any debris or residue from the chair base using a cloth or brush.
This will ensure a clean surface for attaching the new gas cylinder.

Lubricating and Attaching the New Gas Cylinder:

Apply a small amount of lubricant or grease to the connection point on the new gas cylinder.
Insert the gas cylinder into the chair base, aligning it properly with the opening.
Push down firmly until you feel it securely seat into the base.

Reattaching the Retaining Clip or Ring:

Locate the retaining clip or ring that was set aside earlier.
Align it with the groove or slot on the chair base and push it firmly into place until it snaps or locks securely.

The squeaking or creaking sound in an office chair is typically not directly related to the presence of an air cylinder (also known as a gas cylinder or pneumatic cylinder) within the chair. The air cylinder is responsible for providing height adjustment and support to the seat of the chair.

The squeaking or creaking sound usually occurs due to friction between different parts of the chair, such as the seat, backrest, armrests, or wheels. This friction can be caused by a variety of factors, including wear and tear, loose screws or bolts, lack of lubrication, or a deteriorating or damaged component.

To resolve the squeaking issue in an office chair, you can try the following steps:

Tighten screws and bolts:

Check for any loose screws or bolts in the chair’s frame, seat, backrest, or armrests. Using appropriate tools, tighten any loose connections.

Lubricate moving parts:

Apply a small amount of lubricant to any movable joints, mechanisms, or connections in the chair. This can help reduce friction and minimize squeaking noises. Be sure to use a lubricant specifically designed for use on furniture or chairs.

Inspect and replace damaged components:

Check for any visibly damaged or worn-out parts, such as wheels, casters, or the base of the chair. If you notice any issues, consider replacing those components to eliminate the squeaking sound.

Check the floor surface:

In some cases, the squeaking sound may be caused by the interaction between the chair’s wheels and the floor surface. Consider using a chair mat or changing the type of floor surface to reduce friction and minimize noise.

It’s important to note that if the squeaking sound persists or if you are unsure about performing the repairs yourself, it’s recommended to consult a professional or contact the chair manufacturer for further assistance and guidance.


Removing a gas cylinder from an office chair is a relatively simple process that only requires a few basic tools and careful execution. By following the step-by-step instructions outlined in this guide, you can confidently disassemble and replace the gas cylinder in your office chair. Remember to prioritize safety, prepare the necessary tools, and exercise caution throughout the process. With these guidelines, you’ll be able to remove the gas cylinder smoothly and efficiently, allowing for easy repairs or replacements to keep your office chair in optimal working condition.
