Office Chair Cylinder: What Is It and How Does It Work?

|Jul 21, 2022

When you sit for long periods, an ergonomic chair provides the body with the support it needs as they have many features designed to support the user's health while at a desk. They have many advantages for posture and comfort. Ergonomic chairs are usually equipped with a hydraulic office chair cylinder to adjust the seating positions easily and quickly - using a lever under the ergonomic office chair.

Fluid power applications are known as hydraulics and pneumatics. This allows for ergonomic adjustments. A hydraulic system uses an incompressible liquid (such as oil) to move machinery, and a pneumatic system uses an easy-to-compress gas (like air or a pure gas) to facilitate the same function. Compared to a hydraulic chair lift, pneumatic technology is cleaner and allows for moving lighter loads (such as office chairs). It is also safer and easier to store than hydraulic systems. In both systems, technology has been used; however, pneumatics is typically used in office chairs.

What is an Office Chair Cylinder?

What is an Office Chair Cylinder?

Using compressed gas as a source of pressure, pneumatic cylinders force the gas through a chamber that then moves a piston in the desired direction. For the seats of office chairs to move up and down, movement and force are required. This movement is facilitated by the gas being forced into and out of the chamber when the lever is pressed.

With pneumatic chairs, a lever is generally located just beneath the seat, allowing the chair to be adjusted. As the lever moves up and down, the seat rises and falls smoothly. Is this a mechanical process? In a pneumatic chair, there are quite a few components! These include:

  • There are usually three or four wheels on the base of the ergonomic chair;
  • Air cylinders that store compressed air;
  • A seat equipped with an adjustable lever covered by a plate;
  • The back support is padded

How Does It Work?

How Does It Work?

In order to raise or lower your reclining ergonomic chair, you use a lever below the side of the seat. This is known as a gas cylinder, pneumatic office chair hydraulic cylinder, or gas lift. A gas lift chair is different from an older threaded spindle lift chair, in which you turn counter-clockwise to raise and clockwise to lower the chair. Instead, gas lift chairs utilize a compressed air chamber to raise and lower the chair.

Compressed air raises and lowers your seat when a gas cylinder powers it. The lever on your chair engages the cylinder when it is engaged. You can raise your seat by engaging the lever and lifting your weight while releasing your weight from the seat so that the compressed air in the cylinder pushes the piston out of the air chamber. When you push out the piston, the air in the chamber expands, allowing you to lower the seat by activating the lever and pushing with your weight on the seat.

How to Replace

How to replace

Here's where the fun begins. Just kidding, this can not be easy. If you want to replace the old cylinder in your office chair with a fresh new one, you first need to remove the old one.

  • To access the wheelbase of your chair, tip it over. Tap the edge of the tapered bottom of the cylinder with a hammer or rubber mallet.
  • Aim not to hit the retainer clip in the dead center. To remove the column from the base, keep tapping around the edges to loosen the unit.
  • You might be able to remove the retainer clip from the bottom with a flat head screwdriver if you can't get it free.
  • A piston will be released from a cylinder when this is done. You'll have a wheelbase with the empty cylinder column still in there.
  • This can be accomplished by turning the wheelbase upside down and hammering the tapered column until it's free.
  • After the piston head has been removed from the seat base, proceed to remove the piston. A rubber mallet can be used to loosen the piston by tapping around the edge of the top.
  • It should be able to be wiggled free from the seat base once it's a little loose. Then you can add a new office chair cylinder replacement.



How universal are office chair cylinders?

The sizes and styles of all office chairs in the United States and Canada are the same. The outer cylinder has a 2" outside diameter and a 1.1" inside diameter. Each cylinder's edge is slightly tapered to make installation easier.

What to do when the cylinder of an office chair gets stuck?

First, you need to remove the office chair cylinder. Face the base of the chair and reverse the chair. Ensure that the center of the chair can be seen and accessed easily. In the middle of the base, you will find the holding clip. To remove it, you will need a screwdriver or pliers. To remove the clip from the piston, bend it slightly, so it opens. A washer resembles the tire of a car. Remove it by sliding it off the piston. Do this process only if you have to install a chair cylinder replacement.
