Why does my office chair sink?

If your office chair is sinking, it’s likely due to a faulty pneumatic cylinder. Pneumatic cylinders are used to adjust the height of office chairs, and when they’re not working properly, the chair can sink.

There are a few things that can cause a pneumatic cylinder to fail. 

  • One is simply age – over time, the seals in the cylinder can wear out, allowing air to escape. 
  • Another possibility is that the cylinder was damaged when the chair was moved or assembled.

Things you should know when fixing a sinking office chair

When it comes to office chairs, there are many different parts that make up the whole. One of the most important parts is the gas cylinder. The gas cylinder is responsible for providing the chair with height adjustability. Without it, you would be stuck at one height!

  • The gas cylinder is made up of three main parts: the cylinder base, the inner cylinder, and the actuator. 
  • The cylinder base sits in the chair’s 5-star wheelbase and houses the inner cylinder when it’s not extended. 
  • The inner cylinder sits within the cylinder base and attaches underneath the seat. This is where the pressurized chamber and piston are located. 
  • The actuator is a small button at the top of the inner cylinder, next to the chair’s height mechanism. This is what activates the cylinder when pressed.
  • Finally, there is the retaining clip. This sits at the bottom of the cylinder base and helps to keep everything in place.

If you’re ever having trouble with your chair, gas cylinders are a good place to start troubleshooting. With a little bit of know-how, you can easily replace them yourself.

Here are the 5 simple ways to fix a sinking office chair:

1. Lubricating the chair’s joints

Sinking chairs are a common problem, but there is an easy fix! By lubricating the chair’s joints, you can get your chair back to its original height in no time.

There are some pros and cons to this method. 

On the plus side, it is a quick and easy fix. It is also relatively inexpensive since you probably already have the supplies you need on hand. 

On the downside, this method isn’t permanent, so you may have to repeat the process quite often.

Here’s what you’ll need:

  • WD-40 or another lubricant
  • A rag or paper towel

The process:

To lubricate the joints, simply squirt a generous amount of lubricant onto the rag or paper towel. Wipe down all of the chair’s joints, moving the parts back and forth to work the lubricant in. You may need to reapply the lubricant a few times to get the desired results.

2. Using a hose clamp

If your chair is sinking, you can use a hose clamp to fix it. This is a relatively simple process, but there are a few things to keep in mind.

There are a few pros and cons to this method. 

On the plus side, it’s relatively simple and doesn’t require a lot of supplies. 

On the downside, the chair may still wobble if the screws are not tight enough.

Here’s what you’ll need:

First, you’ll need to gather the supplies you’ll need. In addition to a hose clamp, you’ll need a drill and some screws. You’ll also need a bit of padding to put under the chair’s legs. This will help to prevent the chair from sinking in again.

The process:

Once you have the supplies, the next step is to drill holes into the base of the chair. Be careful not to make the holes too big. You want the screws to be snug so that the chair doesn’t wobble.

Next, screw the hose clamp into the holes. Make sure that the clamp is tight so that the chair doesn’t come loose.

Finally, put the padding under the chair’s legs. This will help to keep the chair from sinking in again.

If you’re looking for a quick fix for a sinking office chair, a hose clamp is a good option. Just be sure to have the right supplies and tighten the screws properly.

3. Using a plastic spacer

If your chair is starting to sink, you may be able to fix it by using a plastic spacer. This method has both pros and cons, so be sure to weigh your options before deciding if it’s the right solution for you.

On the plus side:

  • Using a plastic spacer is a relatively cheap and easy way to fix a sinking office chair
  • It can be a temporary fix until you are able to afford a new chair

On the downside:

  • The plastic spacer may not be a permanent solution and your chair may continue to sink over time
  • You may need to replace the plastic spacer frequently
  • The plastic spacer may not provide the same level of support as a new chair

The Process:

Here’s what you’ll need to do if you decide to use a plastic spacer to fix your chair:

  1. Measure the width of the space between the seat of your chair and the floor.
  2. Cut a piece of plastic (a soda bottle or milk jug works well) to fit the space.
  3. Place the plastic spacer under the seat of your chair.
  4. Sit in your chair and see if it feels more supportive. If so, you’re all set! If not, you may need to add more spacers or try a different method.

  • You may need to ask someone for help if you’re not sure how to do it

Here’s what you’ll need to replace the cylinder:

  • A new cylinder

  • Flat head screwdriver

Here’s the process:

  1. First, you will need to remove the old cylinder. There are usually two screws that hold it in place. Use the Phillips head screwdriver to remove these.

The new office chair keeps sinking – How to fix it?

If you’re struggling with a new office chair that keeps sinking, there are a few things you can do to try and fix the issue. First, check to see if the chair is adjustable. If it is, try raising or lowering the seat until it’s at a comfortable height. If that doesn’t work, try adjusting the tension knob
