Gaming chairs are essential for providing comfort and support during long gaming sessions. However, a common issue that many gamers face is their gaming chair sinking or losing height over time.

In this article, we’ll explore a few reasons why gaming chair keep going down, provide solutions to fix this issue, and answer some frequently asked questions related to sinking gaming chairs.

Key Takeaway

If your gaming chair keeps going down, it’s likely due to one of the following reasons:

  1. A faulty pneumatic cylinder: Over time, the seals in the cylinder can wear out, causing the chair to lose height.
  2. A worn-out or damaged hose clamp: If the clamp is not holding the cylinder securely, the chair may sink.
  3. Improper chair assembly: Misaligned components can cause excessive friction on the cylinder, leading to sinking issues.

To diagnose and fix the issue, inspect the chair for visible damage, tighten or replace the hose clamp if needed, and consider replacing the pneumatic cylinder if it’s faulty. Regular maintenance and proper assembly can help prevent sinking issues and extend the life of your gaming chair. ]

Understanding Gaming Chair Mechanics

The role of the pneumatic cylinder

A pneumatic cylinder, also known as a gas lift, is responsible for the height adjustment of your gaming chair.

This metal cylinder underneath the seat contains compressed nitrogen gas, which helps maintain the gaming chair keeps it’s height when you sit on it.

The nitrogen gas creates pressure inside the cylinder, allowing the chair to support your weight at the desired height.

How the gas lift mechanism works

When you pull the height adjustment lever, the gas cylinder releases some of the compressed gas, allowing the chair to move up or down.

The correct height is maintained by the pressure inside the cylinder counteracting your weight.

When the adjust lever is released, the chair’s height should remain stable unless there is an issue with the cylinder or other components.

Common Reasons Why Gaming Chairs Go Down

Faulty pneumatic cylinder


One of the most common reasons for a sinking gaming or office chair, is a faulty pneumatic cylinder.

Over time, the seals in the cylinder can wear out, resulting in a slow release of gas and causing the chair to lose height.

This issue can occur in both gaming chairs and office chairs, as they often use similar pneumatic cylinders for height adjustment.

Worn-out or damaged hose clamp

A hose clamp secures the extendable cylinder to the chair’s base. If the part use a hose clamp is worn out or damaged, it may not hold the cylinder securely, leading to the chair sinking.

In some cases, the hose clamp may become loose over time due to regular use or vibrations from moving the chair.

Improper chair assembly

If the chair components are not aligned correctly during assembly, excessive friction on the cylinder may cause the chair to sink over time.

This issue can be caused by several reasons, by overtightening screws, misaligned parts, or failing to follow the manufacturer’s assembly instructions.

How to Diagnose a Sinking Gaming Chair

Identifying the source of the issue


To diagnose and repair the cause of your sinking gaming chair, first, inspect the chair for visible damage.

Examine the pneumatic cylinder, hose clamp, and other components for signs of wear or breakage.

Pay close attention to the metal cylinder underneath the seat, as this is often the source of sinking issues.

Checking for visible damage

If there’s no visible damage, pull the height adjustment lever while sitting in the chair. If the chair sinks even when the lever isn’t engaged, it may indicate a faulty cylinder or hose clamp.

In some cases, you may hear a hissing sound as gas escapes from the cylinder, which is a clear sign of a leak.

Then, slide plastic tube from the old cylinder out and insert the new one.

Make sure to secure it properly with the hose clamp. Replacement cylinders can be purchased online or at office supply stores, but make sure to select one that matches the specifications of your chair.

Temporary fixes for minor leaks

For minor leaks, you can use duct tape or a PVC pipe method as a temporary fix.

Wrap duct tape around the chair cylinder, to create a barrier that prevents the chair from sinking.

You could measure the diameter and length of the cylinder and cut a PVC pipe to fit over it.

This will prevent the chair from sliding down the cylinder.

While these fixes may not be permanent solutions, they can provide temporary relief until you’re able to replace the cylinder.

Adjusting or Replacing a Hose Clamp

When to tighten the hose clamp

If the hose clamp is loose but not damaged, you can try tightening it to secure the cylinder first place and prevent the chair from sinking.

Be careful not to overtighten the clamp, as this can cause damage to the cylinder or other components.

Replacement hose clamps can be found at hardware stores or online retailers.

Proper Gaming Chair Assembly Tips

Following manufacturer instructions

When assembling your gaming chair, always follow the manufacturer’s instructions to ensure proper alignment and prevent sinking issues.

Regular cleaning and inspection

Proper maintenance of your gaming chair can help prevent sinking issues.

Regularly clean and inspect the entire chair for signs of wear or damage, paying close attention to the pneumatic cylinder and hose clamp.

Keep an eye out for any visible signs of wear on the seals or other components, as this can indicate potential issues.
