How to Fix Sinking Office Chair

Fixing a sinking office chair is no easy task, we know that. However, we’re going to show you two easiest possible ways to complete your task.  You can either use a hose clamp or a PVC pipe to get the job done.

1.Using a Hose Clamp

So, we’re going to talk about the hose clamp first and how you can use it to solve your problem. Go through these easy steps and fix your office chair right away.

Sliding the Plastic Tube

Sliding the Plastic Tube

Office chairs have one common thing, plastic tubes. You’ll find it over the extendable cylinder the chair comes with. Slide it in such a way that it goes either all the way up or all the way down. Keep doing this until you notice the metal cylinder is being exposed.

Adjust the Chair’s Height

It’s time for you to adjust the height of your chair.  Now, you have to remember one thing though. After this repair is done, you won’t be able to adjust the chair’s height. Since this is the last time, you’re going to do it, so make sure you set the height right. Make sure the seat is on the level of your knees as you stand.

Wrap a Hose Clamp

Get your hands on a hose clamp that’s about ¾ inches long. You can easily find it in a hardware store. Now, it’s time for you to loosen the screw you’ll find on the hose-clamp.

Once you’ve unscrewed it, you have to pull the belt-end out. Make sure the clamp is wrapped perfectly around the cylinder. However, it’s still not the right time to tighten it.

See If the Grip is Strong

No matter what, you have to make sure the clamp is very tight so that it can hold the chair up.  You can wrap a strip over rubber or try wrapping few layers of duct tape around the cylinder. This will make sure the clamp has got a better surface for gripping the chair.

Tighten the Clamp

Once you’re done, you’ve to slide the clamp so that it makes its way to the top of the cylinder. You can give it a double check to see if the chair has the right height. Pulling the clamp tight is the next thing you have to do. Lastly, rotate the screw in order to fasten it.

Test the Chair

Now that you’ve done everything perfectly, the chair won’t be able to slide down passing the clamp. Remember, you won’t be able to adjust the height anymore. If you’ve set the wrong height somehow, you have to move the clamp lower or higher.

2. Using a PVC Pipe

If you didn’t find the hose clamp thing easy, you’ll surely find using a PVC pipe pretty easy. Get to the steps below and you’ll be able to fix your office chair in no time.

Measure the Cylinder of Your Chair

You’ll see a plastic skirt that’s covering the metal cylinder; pull it down. Hold a ruler horizontally across it and measure the diameter of the metal cylinder. Then, adjust the height of the chair perfectly, and while it has got the perfect height, measure the cylinder’s length.

Get Yourself a PVC Pipe

Buy a PVC pipe from the nearest hardware store. Make sure it has got the same diameter as the cylinder. A pipe having 1.5 inches of diameter should be enough for almost all the cylinder types. However, make sure the pipe is straight enough.

Starting from the wheelbase of your chair, the pipe should be able to extend to the seat as the chair stays fixed at your desired height settings.

Cut the Pipe Using a Saw

After you’ve secured the pipe in a vise, cut the cylinder using a backsaw or a hack saw. Make sure you go from tip to tip. However, you’ll have to do it on only one side. Cut it in such a way so that you can get a pipe that has a slit with it. It’s not going to be two half-pipes.

As you cut the PVC pipe, don’t forget to wear a respirator or a mask. This will prevent you from inhaling all those irritating particles.

If there’s no vise around you or you don’t have any cutting tool, you just have to leave the PVC pipe intact.  Now, remove the wheels of your office chair. This will allow you to slide on the PVC pipe.

Snapping the Pipe

You see the plastic skirt on the chair? Pull it up or down and you’ll be able to find the metal cylinder. Now bring the slit side of the pipe you just got and push it against the cylinder. Voila! That should keep the pipe snapped all around the cylinder.

This will prevent the chair from sliding down and keep it in one place. If you think the height of your chair needs to be a bit higher, you can raise it and span another slit pipe. 

Wrapping Up!

See? It’s not that tough, is it? Now that you know how to fix sinking office chair, you can solve your problem within minutes.
