It is not only annoying if your office chair won’t stay up. The worse thing is it affects your productivity. When you leave it alone, it looks perfectly fine, but as soon as you sit on it, the chair sinks. How are you going to work when your chair is like this? 

Your first thought must be to get a replacement. Replacing your old office chair would be easy, but if you don’t have the budget yet, why not try fixing it? Let me share with you at least two ways on how to fix an office chair that won’t stay up.

What You Will Need?

For Hose Clamp or Jubilee Clip

  • Hose clamp/jubilee clip long enough for the whole cylinder
  • Duct tape
  • Screwdriver

For the PVC Pipe Method:

  • PVC pipe (must be the same size or larger as the cylinder of your chair)
  • Tape measure
  • Vice
  • PVC-cutting tool or saw

You can easily find the materials for both methods in your house or the nearest hardware. Both methods are simple enough to do on your own. But it might be a little hassle to have to cut the PVC on your own. In that case, you might want to choose the hose clamp/jubilee clip method.

How to Fix an Office Chair that Won’t Stay Up – Step by Step Instructions

Follow the steps below on how to fix your office chair that won’t stay up.

  • Hose Clamp/Jubilee Clip Method
1

Slide off the Cylinder’s Plastic Skirt

Office chairs often have a plastic tube wrapped around the cylinder. Take this off, so that the metal cylinder is now visible. 

2

Adjust the Chair to Your Preferred Height

Before fixing the chair, adjust it first to your preferred height. Remember to make this right as you won’t be able to adjust it again unless you undo the work. When setting the height, the chair should be around the level of your knees when standing. 

3

Wrap the Hose Clamp/Jubilee Clip Around the Cylinder

Once you set your preferred height, loosen the hose clamp or jubilee clip’s screw, pulling out the belt end. After this, wrap the device around the metal cylinder without tightening it yet.

4

Wrap Duct Tape or Rubber to Improve Clamp Grip

It is likely the clamp isn’t the exact size, which means it won’t be tight enough to hold up the chair. That’s why I strongly recommend that you improve the clamp’s grip by wrapping up some duct tape or strip of rubber around the cylinder. 


Don’t forget to clean or scuff up the cylinder first if it is dirty or greasy. Otherwise, the rubber or duct tape will not work well in giving the device a better surface. Also, wrap the rubber or duct tape only on the cylinder’s highest visible point. 

5

Tighten the Hose Clamp/Jubilee Clip 

After improving the surface, slide the clamp to the cylinder top. Make sure that the chair is the correct height before you pull the clamp tight. Rotate the screw as far as possible to fasten it, ensuring it will hold the chair really well. 

6

Test Your Office Chair

When you are done, the chair shouldn’t be able to slide down past the hose clamp. It also means the height adjustment won’t work. It is why I said that your chair has to be the right height. If it isn’t, you will have to redo the steps above, moving the clamp higher or lower as desired. 

  • PVC Pipe Method
1

Measure the Cylinder

Start by sliding the cylinder’s plastic cover off. Get a ruler to measure the cylinder horizontally to estimate its diameter. Also, measure how long the cylinder is after adjusting it to your ideal height. The diameter doesn’t have to be precise, so don’t worry about it too much. 

2

Buy Enough PVC Pipe

The pipe will cover the pneumatic cylinder, so its size should be about the same or a bit larger. Make sure to buy enough PVC pipe, probably well over the length of the wheelbase to the chair seat. Buying smaller pieces of a pipe is ideal, so you don’t have to cut them yourself. 

3

Saw through the Pipe Lengthwise

Use a vice to secure the pipe. Cut it from tip to tip using a saw or any PVC-cutting tool. Make sure that you only cut the pipe on one side. Cutting the pipe should result in a PVC with a slit in it.

4

Snap the Pipe Around the Cylinder

Take the pipe and push the slit side against the metal cylinder. Doing so should snap the pipe around the cylinder, wrapping it. With that, the pipe will be able to hold the seat in place and prevent it from sinking. 

5

Add Another Pipe to Adjust Height

Cutting the pipes in a shorter height is ideal for easy snapping. Also, it makes it easier to add more pipe when adjusting the height of the chair. Remember you won’t be able to lower the height again unless you remove the pipes.
