Method 1 – Replace the Gas Cylinder

Method 2 – Use PVC Pipe

This is a temporary method, so let me tell you that before beginning. If you use this method, you will not be able to adjust the chair height until you remove the PVC pipe. If you use this method, the chair will be fixed at any height you want. So now let’s move to the method. Make sure to buy high-quality PVC pipe from the market.

  • First take a PVC pipe. And make sure that this pipe should be bit same diameter and height of your cylinder cylinder piston.
  • Also it should be much wider then your cylinder piston size. So that PVC pipe didnt go inside the cylinder piston.

After getting the correct size PVC, lay the chair on the floor. Working on the chair will be much easier. Adjust the chair to your desired height. Using the PVC pipe you just cut, wrap it around the gas lift cylinder piston. This will fix the chair to that height.

The chair will not sink until you don’t take out that pipe. If you dont like the height then just take out that PVC pipe and then adjust the height and again put the pipe in the chair. As I said this method has some drawbacks but this is one of the easiest and cheapest methods. It won’t cost you more than 10-15 Dollars.

Method 3 – Fix using hose clamp and Duck tape

This method is also temporary and has drawbacks like the PVC pipe method like you can’t adjust the chair height. This method can give you a problem again after some time. That is why we don’t recommend this method. First, we will talk about how you can fix it through a hose clamp.

  1. First buy the hose clamp from amazon or offline market.
  2. Get the hose clamp according to your cylinder piston diameter.
  3. Now first adjust your chair height to your desired height.
  4. After that, now just put hose clamp under over the cylinder piston.
  5. If your hose clamp dont get much tighter then you cab first wrape the Duck tape over the piston. As it will prevent the hose clamp from going down.
  6. After that your chair seat will get stuck at that height and wont come down even after you sit on the chair.

The method will not cost your more the 1$. And also you can do this method easily at home.
