7 Best Gas Lift Cylinders for Office Chair: Reviews and Buyers’ Guide for Chair Pneumatic Lift

The best gas lift cylinder for your office chair will depend on the dimensions of the chair you have. While we recommend going for a replacement from the same manufacturer, this may be a bit hectic. Rather, getting a universal gas lift cylinder will be enough for most chairs.  

Knowing how a gas lift cylinder works is important since it allows you take proper care of it and replace it when time comes for a new one. Even with the best care, gas lift cylinders will eventually get worn out and need replacement. Gas lift cylinders for chairs don’t have parts you can replace and instead require complete replacement. The good news is that even the very best of them cost a few tens of dollars hence easily affordable.  

In choosing the right gas lift cylinder for your chair, always consider the stroke of the cylinder. This is the distance the chair can travel from the highest to the lowest point. This will determine how high the gas lift cylinder (also called the plunger piston or hydraulic shaft) can raise and lower your chair.

Buying Guide: What to Look for in an Office Chair Gas Lift Cylinder 

Gas lift cylinders may appear similar but there are some specific differences among them. These differences are what determine which cylinder to go for. They include the following: 

1. The amount of stroke/travel 

The stroke of a gas lift cylinder or chair refers to the distance between the highest point and the lowest that the chair can attain. It’s primarily determined by the gas lift cylinder and is fixed for each cylinder. Most gas lift cylinders will have a stroke of about 5 inches. This means that the chair will rise from the lowest point to 5 inches upwards.  

You need to choose the right stroke for your chair as it determines your comfort. If you get one that’s too short, your chair won’t rise to the height you need. Our advice is that you get one that’s just the height of your current gas lift cylinder (or longer if you want a higher chair).  

The easiest way to measure the travel of your chair or gas cylinder is to lower it completely then mark on the wall the top part of the back. Fully raise it then mark the new position of the top of the back of your chair on the same wall. The distance between the two marks is the current travel of your chair and gas lift cylinder.  

2. Size (fit) 

The size or fit of your chair is another determinant of whether a gas cylinder fits your needs or not. This refers to the size of the cylinder in terms of the gas spring and the column. The gas spring is the top part of the cylinder and is what goes into the chair tilt mechanism below the seat of the chair. 

In a standard chair, the gas spring has a diameter of 1.1 inches (28mm). It also holds pressurized nitrogen gas and lubrication oil. At its very top is a tapering of 17-4 for an industry-standard chair. The gas spring also has the piston (the shiny cylinder) that moves up and down when adjusting the chair height.  

The column of the gas cylinder is the circular part that goes into the base of the chair and houses the gas spring. It’s usually black in color for most gas cylinders. The industry-standard column has a diameter of 2 inches.  

3. Materials and build quality 

The material used to make the gas lift cylinder will determine its quality and longevity as well. All gas lift cylinders are a combination of metal and plastic and are classified into classes with Class 4 being the best quality. Class 4 gas lift cylinders are made of heavy-duty steel and hard plastic for longevity.  

Besides the materials, the quality of the build will also largely determine the longevity of the gas lift cylinder. The cylinders work by use of the pressurized nitrogen gas which allows for the raising and lowering of the chair. If the nitrogen gas escapes due to a poor build quality, the cylinder won’t work properly.  

4. Ease of replacement 

Removing the old cylinder and replacing it with the new one is among the most challenging procedures when replacing a gas lift cylinder on your chair. With the gas lift cylinders above, the procedures are quite direct and can be done in a few minutes with the right tools. Some of the gas lift cylinders here come with the needed tools in the case that you don’t have them at the ready. Generally, the easier the procedure, the better the gas lift cylinder.  

5. Total length of cylinder (protrusion below chair base) 

Besides the stroke of the gas lift cylinder, the other aspect to consider is its total length. That’s the length from the top of the gas spring to the bottom of the column. This determines how much of the cylinder will protrude below the base when the cylinder is fitted to the chair. 

If there’s too much of the cylinder below the base, it means that the cylinder you chose is too long. This can hinder the other functions of the chair such as rotations and moving around. If there’s too little of it, the chair will not be stable and it’s a sign that the gas lift cylinder is too short. 

The safest way is to measure the total length of the current gas lift cylinder on the chair then pick a similar length as a replacement. Measure it when compact and fully distended then match the measurements of your current cylinder to the measurements of your intended replacement. 

These aspects will give you the gas lift cylinder you need for your chair. For a few tens of dollars, you can restore and even improve the workings of your chair in no time. Keep in mind that you don’t need to get an exact replica of the gas lift cylinder currently on your chair. As long as it matches the measurements and it’s a quality one, it’ll serve you well. If your gas lift cylinder can’t get you to the height you want, you can make your office chair higher with our guide here. On the other hand, if you simply want an office chair for a big guy, have a look at this guide.

Are Office Chair Cylinders Universal?  

No. Different office chairs come with different measurements for their gas lift cylinders although the working mechanisms are the same. However, there is an industry standard to which a majority of office chair gas lift cylinders conform to. These have an external diameter of inner and outer diameters of 1.1 inches and 2 inches respectively. The other dimensions such as the height can differ but it’ll still be a universal fit.
