Office Chair Cylinders

You may not realize it, but your office chair plays a huge role in making your work environment more productive!

A good office chair provides excellent pelvic and lumbar support for better posture. This results in a chain reaction of better breathing, less fatigue, and relaxed back muscles.

An ergonomic office chair is just what you need to increase your workplace productivity.

One of the most crucial factors when choosing an office chair is the height of your seat. To find the correct seat height, you’ll need to find a gas cylinder that corresponds to your height.

In this article, we’ll discuss how you can find the ideal cylinder size for your chair.

Before we get into detail about the steps to find the right gas cylinder replacement, let’s find out how a gas cylinder works and if it’s universal for all office chairs.

Let’s begin!

What’s the best office chair height?

A gas or pneumatic cylinder is responsible for moving your chair seat up and down.

With the ideal ergonomic chair height, your legs should be supported at all times. The right cylinder adjusts your office chair to your height so that:

  • Your feet lie flat on the floor
  • Your knees are bent at a 90-degree angle

How does an office chair cylinder work?

Gas cylinders take the pressure from compressed gas and force it through a chamber. The pressured power then moves the piston to the desired position.

When you engage the lever on your office chair, it activates the cylinder.

When you press the lever while releasing your weight from the seat, the piston shoots out of the chamber and raises your seat.

Once you push down the lever and apply your weight to the chair, the seat will lower.

Parts of a Gas Cylinder

Stand Pipe or Outer Column: This connects the cylinder to the chair’s base. Standard pneumatic chair cylinders have a standpipe diameter of 2 inches. According to the manufacturer, standpipe heights may vary in length, but the two-inch diameter is the same for most office chairs.

Piston or Inner Column: The piston connects to the seat base and is responsible for raising or lowering your chair height. It has a diameter of 1.1-inch, and the top connects to the seat base (swivel unit).

Actuator: This button on top of the piston pushes and activates the cylinder to raise or lower the chair.

Retainer clip: This prevents the bottom of the piston from sliding out of the outer column.

Now that you’re familiar with the parts, you’re probably wondering if all office chairs share the same gas cylinder size.

Most office chair gas cylinders are universal. The main difference between standard gas cylinders is how high they make your seat.

Most gas cylinders will be five inches long. However, other cylinders range from four to ten inches depending on the chair type. Most chair manufacturers will offer gas cylinders between four, five, and six inches.

Step-by-step Guide: How to find the best cylinder size for your office chair

To find the ideal ergonomic chair height for you, you will need to choose a gas cylinder that corresponds to your height.

Here’s how:

Step 1: Measure your Height

The best cylinder size corresponds to your height:

If you’re less than 5 ft. 4 in., get a four-inch cylinder.

If your height is between 5 ft. 4 in. to 6 ft. 2 in., get a five-inch cylinder.

If you’re taller than 6 ft. 2 in., get a six-inch cylinder.

Step 2: Measure your Seat Height

The next step is to measure your seat height.

Sit on the chair with your feet planted on the floor. Your knees should be at a 90-degree angle and your thighs parallel to the floor.

To get your seat height, get the measurement from the base of your knee cap to the floor.

Step 3: Measure your Seat Height With Different Shoe Types

When finding your minimum and maximum seat height, wear flat shoes and high-heeled shoes.

Step 4: Measure Chairs from Different Manufacturers

While different manufacturers share a universal and standard gas cylinder size, some will have different seat heights.

Now that you know your ideal seat height and gas cylinder size, you’ll be able to find the ergonomic office chair of your dreams!

The next step is to find a replacement gas cylinder for your office chair. Then insert it into your wheelbase and seat.
