Keeping the surroundings clean and tidy while removing and replacing the base of a desk chair is a good idea. It will prevent the post-cleaning efforts. So, use a plastic mat to cover the floor.

How to Handle Stuck Office Chair Base?

It's not always so easy to remove the base of the office chair. Sometimes, it may get stuck inside, and you face a great inconvenience in removing it. However, it's possible. In such a case, follow these steps.

Put the Chair On Plastic Sheet

As mentioned above, put your desk chair on a plastic sheet with the downside up. You may also consider flipping it on either side.

Spray Lubricant on the Gas Cylinder Cover

As the gas cylinder cover doesn't let the base come out, it's good to use any lubricant. Spray the lubricant on the gas cylinder cover that will make it slippery.

Make sure that the lubricant reaches each side and bottom of the cylinder. Covering the sides of this cylinder will avoid the mess in the surrounding area.

Hit the Base With Mallet

After lubricating the cylinder, leave it for some time. Then take a mallet and start hitting the base in an outward direction. It will start moving outside.

Keep hitting the base gently unless it comes out. Here you have done it.

Can I Remove All Office Chair Bases With the Same Method?

Having read all the procedures mentioned above, you may know whether these methods will work for your chair or not. The question “Do all office chairs have the same base?” may confuse you. But don't get confused; a simple answer to your query is Yes.

Almost the base of all the office or desk chairs are the same regarding their attachment sizes. The thing that differentiates them is the material used to manufacture them and their finishing process. Here are the most frequently used materials for such chairs' bases.

  • Plastic
  • Steel
  • Aluminum
  • Wood
  • Metal

Some chairs come with wheels, while others have simple legs. Those having wheels will be more comfortable and easy to move, but their bases will be damaged earlier. On the other hand, chairs featuring just legs will still be more durable, and their bases will last longer.
