You are fully aware of how to fix an office chair that won’t stay up, and it is not a great deal as adjusting the chair’s pneumatic cylinder is quite an easy task. There are some common tricks to fix an office chair. But, before changing the chair, you need to analyze the typical mistakes causing the sinking of your chair.

Analyze the inner workings of the Pneumatic Cylinder of the office chair
If you do not fix your office chair, it will cause further investment. But, if you want to save your money, you need to identify the workings of a pneumatic cylinder. The working of the cylinder and height adjustments depend upon extreme air pressure. When you elevate and lower the height of your chair, air pressure will control the height adjustments by controlling the valve.
When air pressure remains constant in the cylinder of the chair, you can easily adjust the height of the chair. A seal of the cylinder keeps airtight. But when air pressure starts leaking, chair sinking occurs. All in all, faulty sealing is the primary source of air pressure.
Many gas lift cylinders are present in the market according to build quality and sealing. Still, the perfect office chair is a class 4 gas cylinder that provides excellent air pressure, but sometimes, it also causes air leakage.
But, unfortunately, changing the air sealing is not easy as it can cause an explosion of air pressure. But, if you want to solve the chair sinking problems, there are the following easy hacks to fix the issue of the pneumatic cylinder.
What is a Pneumatic Cylinder?
A pneumatic cylinder in an office chair is a type of gas spring that uses compressed air to adjust the height of the seat. It is a key component of most modern office chairs, as it allows users to easily adjust the height of their seat to their liking.
The cylinder consists of a hollow tube with a piston inside. When compressed air is pumped into the tube, it pushes the piston upwards, which raises the seat. The amount of pressure in the cylinder can be adjusted to allow for greater or lesser force required to raise or lower the seat.
The pneumatic cylinder is a simple and efficient mechanism that allows for easy adjustability and customization of office chairs, making them more comfortable and ergonomic for users of different sizes and preferences.
Use PVC Pipe Method
A PVC pipe or a plastic spacer is a perfect but temporary solution to solve the sinking chair issue. This piece of PVC pipe adjusts around the piston of the cylinder. When you change the seat height, this pipe will support the cylinder. At the start, analyze the already present seat height that needs to be fixed and then cut the pipe accordingly. You also need to cut the pipe in a larger width than the cylinder. Within no time, this method will solve the chair sinking issue. There are the following steps to use the PVC pipe method.
- In the first step, measure the height of the chair and the cylinder’s diameter. In this way, you can find a good size PVC pipe.
- Now, lift the plastic skirt and mark it on the cylinder.
- Now, mark a rather large PVC pipe then the cylinder size,, and cut it with an electric cutter or a saw.
- We suggest cutting the PVC pipe in two or three steps as one single line causes more trouble.
- In the last, Snap the PVC pipe or two pieces of pipe into the cylinder of the chair. Cover the cylinder with duct tape to enhance the pipe grip.
