Step-By-Step Guide: How To Remove An Office Chair Piston

Are you tired of your office chair sinking every time you sit down? The culprit may be a faulty piston.

Luckily, replacing a piston in your office chair is a simple process that can be done with just a few tools and some patience. In this step-by-step guide, we will walk you through the process of removing an office chair piston so you can fix your chair and get back to work in no time.

Before we begin, make sure you have all the necessary tools on hand. You will need a rubber mallet, pliers, a screwdriver, and a replacement piston.

Once you have gathered your tools, we can get started on removing the faulty piston. By following these steps, you can easily remove the old piston and install a new one, ensuring that your office chair is comfortable and functional once again.

Gather the Necessary Tools

You’ll need to grab some tools before you can start removing that office chair piston, so let’s get to it! First, you’ll need a rubber mallet or hammer and a pry bar or screwdriver. These will help you to loosen and remove any components that are holding the piston in place. You may also need pliers or a wrench to grip and turn certain parts, depending on the type of chair you have.

Once you have your tools, it’s important to make sure you have a safe and secure work area. Lay down a drop cloth or old towel to protect your floor from scratches or damage. Then, adjust your chair to its lowest setting and turn it upside down so that you have access to the base and piston. Be sure to wear gloves and safety glasses to protect your hands and eyes.

Now that you have your tools and workspace set up, you’re ready to start removing that pesky piston. Use your rubber mallet or hammer to gently tap the base of the chair to loosen any components. Then, use your pry bar or screwdriver to carefully pry off any covers or caps that may be concealing the piston. With these removed, you should be able to see the piston and its attachment points more clearly.

Remove the Base and Wheels

First, loosen the screws that attach the base to the chair using a screwdriver. This will allow you to remove the base from the piston and access the wheels. Once the screws are loose, lift the base off the piston and set it aside.

Next, remove the wheels from the base by gently pulling them out of their sockets. Be careful not to lose any small parts or screws while removing the base and wheels. Keep them in a safe place where they won’t get lost or mixed up with other parts. You may want to use a small container or bag to store them until you’re ready to reassemble the chair.

With the base and wheels removed, you can now focus on removing the piston from the chair. This will require a bit more effort, but it’s an important step in the process. Keep reading to learn how to remove the piston from the chair.

Remove the Gas Lift Cylinder

To remove the gas lift cylinder, start by flipping the chair upside down and locating the retaining clip that holds the cylinder in place. The retaining clip is a small metal ring that is positioned around the bottom of the cylinder. Use a pair of pliers to gently pull the clip away from the cylinder. Be careful not to damage the clip as it’ll need to be reused.

Once the retaining clip has been removed, grip the cylinder firmly with both hands and pull it out of the chair. If the cylinder is stuck, try twisting it back and forth a few times to loosen it. If this doesn’t work, you may need to use a rubber mallet to gently tap the cylinder until it comes loose.

With the cylinder removed, you can now replace it with a new one or clean it if it’s still in good condition. To install a new cylinder, simply slide it into the chair base and replace the retaining clip. Make sure the clip is securely in place before flipping the chair back over.

Congratulations, you’ve successfully removed the gas lift cylinder!

Remove the Retaining Clip

Now it’s time to get that retaining clip off so you can move on to the next part of the process! This can be a bit tricky, but with some patience and the right tools, you can easily remove it.

Start by using a pair of pliers to grip the clip firmly, making sure not to damage it. Next, twist the clip counterclockwise while pulling it upwards. This should release the clip from the piston, allowing you to remove it completely.

If you’re having trouble, try wiggling the clip back and forth while pulling upwards to loosen it up.

Once the clip is removed, you can pull the piston out of the base of the chair. Congratulations, you’ve successfully removed the piston! Now you can move on to replacing it or fixing any other issues with your office chair.

Remember to save the retaining clip, as you’ll need it when it’s time to reassemble the chair.

Remove the Piston

After successfully taking out the retaining clip, it’s time to proceed with taking out the piston from the base of the chair.
The first step is to lift the chair up and flip it over so that the base is facing upwards. You’ll be able to see the piston sticking out of the base.

Next, you need to grip the piston firmly and pull it out of the base. Be careful not to damage the piston as you remove it, as it may still be in good condition and can be reused. If the piston is stuck, you can try using a lubricant such as WD-40 to help loosen it up.

Once you’ve removed the piston, you can inspect it for any signs of damage or wear and tear. If it’s in good condition, you can reuse it for your new chair. If it’s damaged, you’ll need to purchase a new piston before you can continue with the installation process.

With the piston removed, you’re ready to move on to the next step in the process.

Install a New Piston

Are you ready to give your office chair new life? With the old piston removed, it’s time to install a new one to get your chair back in working order. Here’s how to do it:

First, make sure you’ve got the correct replacement piston for your chair. Check the measurements and specifications to ensure a proper fit. Once you have the new piston, you can begin the installation process.

To install the new piston, start by inserting the bottom end into the base of the chair. Make sure it’s lined up properly and press down firmly until it clicks into place.

Then, slide the top end of the piston into the chair seat mechanism and again, press down firmly until it clicks into place.

Finally, test the chair by lifting it up and down a few times to ensure the piston is securely in place and functioning properly.

Remember, a faulty or improperly installed piston can be a safety hazard, so take your time and make sure everything is done correctly.

With a new piston in place, your office chair should be functioning like new, giving you the support and comfort you need to get through those long workdays.

Reassemble the Chair

Get ready to experience the comfort of your revamped chair as you piece it back together with ease.

Once the new piston is installed, it’s time to reassemble the chair. Begin by turning the chair base upside down and placing it on a stable surface.

Next, insert the piston into the center of the chair base and ensure it is securely in place. Then, slide the chair mechanism onto the piston and align the screw holes. Use the screws that were removed earlier to attach the mechanism to the piston.

Reattach the chair seat by lining it up with the mechanism and tightening the screws.

Once everything is securely in place, flip the chair back over and test it out. Your chair should now be as good as new and ready for all-day comfort!


Congratulations! You’ve successfully removed the office chair piston and are one step closer to fixing your chair. Remember, safety is key when working with tools and machinery. Always wear protective gear and work in a well-lit and organized space.

Now that you’ve removed the old piston, it’s time to install a new one. Make sure to purchase a piston that’s compatible with your chair and follow the instructions carefully.

Once the new piston is installed, reassemble the chair and test it out to ensure it’s functioning properly. With a little bit of effort and patience, you can save money by fixing your office chair instead of purchasing a new one.

Best of luck!
