Your chair can even be brand-new, and it still sinks. We know that you’re growing tired of this problem, and you want to understand how this happens.

This article would bring you the real reason why your chair sinks. You also don’t need to throw it away or contact the store managers since you can quickly fix this problem. Read on and maybe find a solution that is right for your chair.


The Reason Why Your Chair Keeps Sinking

Your chair doesn’t really sink ‘just because.’ There are tons of reasons your chair sinks, and the one to blame is your gas cylinders.

Modern height-adjusting chairs have two different mechanisms that they use. These two types are hydraulic and pneumatic. However, chairs that have a sinking problem use pneumatic cylinders.

Your pneumatic cylinders are responsible for the height adjustment of your chair. These cylinders are located below the seat of your chair and controlled by a lever.

Gas cylinders often stop working when the cylinder’s seal has worn out. This situation results in the air inside the cylinder to escape thus making your chairs sink.

You can experience sinking, primarily if your chair is being used excessively. People who work from home and students who take online classes are the most vulnerable to this issue.

However, having this problem can easily be solved. You can even prevent it with suitable measures.


How Do Chairs Go Up And Down 

Knowing chair mechanisms can help you understand the sinking of your chair in a more straightforward way. Pneumatic chairs and hydraulic chairs are height-adjusting chairs that implement ergonomics. This is also the reason why these chairs are often called ergonomic chairs.

Pneumatic chairs combined ergonomics and pneumatic systems. It can be seen how the chairs are built.

Gas or pneumatic cylinders are containers for compressed gas that move with a piston or a lever. This simple mechanism makes the chair go up and down.


How To Stop Your Chair From Sinking

Good news for you! You don’t need to throw away your sinking chairs and buy a new one. You can fix it with just a few steps and say goodbye to the minor inconveniences you experience.

We list some solutions that you can try on your own chair. You can use available tools in your home or local stores and fix your chair’s lifting functionality with the most manageable steps.


Method #1. Lubricate

Lubricating furniture parts which constantly move seems like common sense to us. This applies to squeaky doors and chairs but can also be done with your gas cylinders. It also extends your chair’s lifespan and prevents damage for a long time.

Gas cylinders can also have rust due to moisture and air conditioners. This goes the same for the screws and bolts in the chair.

Apply or spray lubricating oil to those metal parts to avoid rusting and sinking. You can do this regularly and maintain your chair in its best condition.


Method #2. Using duct tape and jubilee clamp

Use a duct tape and hose or jubilee clamp to stop your chair from sinking. This method is not exactly a solution, but it does stop your chair from working.

Place your clamp around the piston and use tape to keep it secure. This method can work for a few days but slide off again. You can do this temporarily if you don’t have time to repair your chair.


Method #3. Using PVC pipe

First, purchase a PVC pipe that is slightly larger than the cylinder itself. Measure it according to your cylinder’s standard height and width. Adjust your chair to its perfect height to measure it efficiently.

Now, cut one side of your pipe vertically (don’t include the center). After cutting, you can place the pipe on the chair. Snap it on the cylinder and get ready to test your chair out.

This method is similar to the former one as the pipe can break when used excessively. There is a risk, but this method can work out fine; you only need to check it regularly.


Method #4. Replace gas cylinders

This approach is the one to use if you want a more lasting solution. Replacing your gas cylinders with brand-new ones can give you the satisfaction you’ve been yearning for.

Purchase gas cylinders from the store and replace them in the most possible time. Doing this can significantly increase your productivity.



Say goodbye to those days where you ask, “why does my chair keep lowering.” You can now stop wondering and know that your gas cylinders are the ones at fault.

Fix your gas cylinders or replace them. Increase your productivity level without the inconveniences and frustration a sinking chair can give to you.
