How does a swivel chair work?

A few months ago, I was curious about the swivel mechanism of office chairs and wanted to know how a swivel chair actually works. So I did some digging, and this is what I found.

How does a swivel chair work? The swivel mechanism is not anything sophisticated as you might think. The gas cylinder of the chair and internal piston within allows the upper part of the swivel chair to rotate both clockwise and as well as anti-clockwise. This is how a swivel chair works, and up to 360 degrees of rotation is obtained.

However, the swivel mechanism can actually vary along with brands. The full mechanism might seem more complicated than it actually. If you want to know more about swivel chairs and their mechanism, keep reading!

What is a Swivel Chair?

Basically, a swivel chair can be defined as a chair that allows 360-degree rotation with the central leg’s help. The central leg actually helps the chair to move both clockwise and anticlockwise.

A Little History:

The swivel chair was first introduced by a person named Thomas Jefferson around in 1776. It is said that on this first swivel chair, he drafted the declaration of Independence of America in the same year.

The swivel chair that Jefferson invented had no wheels. He did some tweak and modifications to a Windsor chair that he purchased Francis Trumble. He joined the upper and lower part of the Windsor chair through a central iron spindle, which enabled the upper part of the chair to rotate.

As I have noted earlier that it is believed the declaration of America’s independence was written on this chair, it had historical value. That’s why the chair is currently preserved by the American Philosophical Society, Philadelphia. The chair has been under their possession since 1836. [Source]

How does an Office Chair Swivel Mechanism Actually Work?

You might have seen how a car wheel can actually spin without coming off. The swivel mechanism of an office chair is more or less the same. However, there are some variations among different brands. But the basic function are more or less similar.

The gas cylinder of an office chair has an internal piston. This internal piston compresses the gas inside the cylinder when it is pressurized while sitting or some weight is put on it. There is a friction clamp that holds the rod of the piston. This clamp’s function is positioning the height.

There is a lever that releases the friction clamp when the seat is low. This lets the piston to come upwards, carrying the chair’s weight. But when someone sits on the chair, the pressure exceeds the piston’s capacity to hold the chair up. Thus the chair goes downwards due to the weight of the person sitting.

This is a general idea about the internal components and their functions, making sure that you understand the swivel mechanism better.

So now let’s come to the main point, which is the swivel mechanism.

The internal piston and the gas cylinder allow the upper part of the chair to rotate both clockwise and anticlockwise up to 360 degrees as it is resting on the piston, which provides the low resistance rotation ability.

Some brands use bearings to make the chair swivel all around. The seat post is established in the bearing, which is situated near the starbase of the chair. There are steel balls inside the bearing. These balls allow the rotation of the inner part of the bearing while keeping the outer part of the bearing fixed.

The central leg is attached to the bearing, and with the help of the bearing, the chair gets the ability to swivel.

The above-mentioned swivel mechanisms are the basic and most common ones out there. As I have noted earlier, the swivel mechanism actually varies from brand to brand. Some brands also use screws and springs. The swivel mechanism of some office chairs can get more complicated and hard to explain.

I think you got a good insight into how the swivel chair actually works and its mechanism. Now, let’s discuss its functions, and I believe this will provide a better insight into the swivel mechanism.
