Have you ever wondered, Why does my office chair keep going down? You are not alone. A sinking office chair is a common workplace problem that may interrupt concentration, influence posture, and even lead to long-term pain. Whether you’re working long hours at your desk or enjoying a quiet session with a book, having the most comfortable office chair for long hours or the best chair for reading is essential to maintain proper posture and comfort.

The first step to solving this issue and having an ergonomic working environment is to understand why your chair is sinking. This article explores the reasons, diagnosis, preventing future problems, and tips on selecting durable office chairs.

Common Reasons Your Office Chair Keeps Sinking

A defective gas lift cylinder normally leads to a sinking office chair. With the passage of time, the pressure inside the piston is lower than before and is unable to sustain the body weight, leading to a slow or abrupt sinkage of the chair.

A worn-out height adjustment system may be one of the causes. The lock that is used to keep the seat elevated can be weakened by frequent adjustments, heavy use, or low-quality material. The accumulation of dirt and debris in the cylinder may also disturb its functioning of the same. Poor-quality chairs, particularly those in the low-grade variety, are likely to prematurely tip over as a result of poor construction and low-quality components.

How to Determine What Issues Cause an Office Chair to Sag

When you are unsure whether your office chair is sinking, you can find it in the following ways.

• Check the height adjustment level: If it is loose or does not offer any resistance, the locking mechanism can be broken.

• Track how the chair sinks: When you are sitting or as time goes by, if the chair suddenly drops, it means that there is a severe gas lift failure, whereas when it sinks slowly, it means that the cylinder is losing pressure.

• Inspect the gas cylinder: Look for the gas cylinder on whether it has scratches, dents, or oil leaks, which would cause pressure loss.

• Listen for unusual sounds: When adjusting the height of the chair, if there are some different sounds, like a hissing noise, which may indicate there is internal pressure escaping from the cylinder.

These tests will assist you in determining the cause of your office chair constantly sinking and will lead you to the right solution.

How to Fix a Sinking Desk Chair

After examining the issues causing the office chair to sink, it’s necessary to address them for a better sitting experience. Here are some resolutions to help you. 

Tighten or Replace the Height Adjustment Lever 

You can try to tighten the screws around the lever first. But if the lever still cannot properly lock the chair height, you should replace the entire locking assembly to restore normal height control.

Replace the Gas Lift

If there is a gas lift failure, the only effective solution is to replace it with a compatible gas lift cylinder. But the price won’t be expensive, because most office ergo chairs use standard cylinders, making the replacement quick.

Add a PVC Pipe Temporary Fix

If the cylinder loses pressure due to scratches, dents, or oil leaks, the long-term solution is also to replace the gas cylinder; however, you can install a PVC pipe sleeve around the metal cylinder to prevent it from sliding downward as a temporary fix. This method locks the height in place but disables height adjustment.

Address Internal Pressure Leaks

If you hear the hissing noises while adjusting the chair, this indicates that the seals inside the cylinder are worn. Since the seals cannot be serviced, replacing the gas lift is the recommended fix. After installing a new cylinder, apply silicone lubricant to moving parts to ensure smooth operation.

How to Prevent an Office Chair Keeps Going Down

The first step towards preventing this would be to invest in an office chair of good quality featuring a good gas lift. Do not lean far back, and this strains the cylinder even more. Frequent cleaning and servicing also contribute to extending the life of the chair.

Minimize the use of high and low position changes because continuous pressure variations increase wear. Sitting on a high-quality chair properly makes one less likely to experience the same problems and even eliminates the problem of a sinking chair.

Signs That It's Time to Replace Your Office Chair

If the chair continues to sink after repairs, replacement is necessary. Other warning signs include wobbling, unstable wheels, flattened seat cushions, or back support that no longer holds its shape.

Chairs over 5–7 years old often exhibit structural wear. Loose armrests or uneven seating are indicators that upgrading to a new chair will enhance both comfort and productivity.
