Crandall Office Furniture’s Herman Miller Aeron aftermarket stool gas cylinders have been constructed to meet original OEM chair specifications and are built to last.
A office chair gas cylinder is the height adjustment mechanism on the chair. The typical life span of a office chair gas cylinder is 4-7 years, depending on use and abuse. If failed, your chair will be left with limited or no height adjustment, however you can quickly and easily replace your broken Herman Miller Aeron stool gas cylinder today.
Our Herman Miller Aeron Classic gas cylinders are made to fit all Herman Miller Aeron Classic chairs using the top activated style gas cylinder (manufactured before 06-26-2013).
This gas cylinder will not work with the newer remastered style Aeron chair.
This cylinder can successfully be used on a standard Herman Miller Aeron chair, to convert it to stool height, standing desk, sit-to-stand desk, or bar height. Also available is our full stool conversion kit (including foot ring) for the Herman Miller Aeron chair.
If looking for a standard stool height, please consider the 8″ stool cylinder, the 10″ cylinder provides a significant increase in sitting height of the chair, and should only be considered if the 8″ stool cylinder does not reach high enough.
- Overall Length / Maximum Extension: 28.25″
- Overall Length / Minimum Extension: 18.50″
- Amount of adjustment: 9.75″
We have included installation instructions to help you install your aftermarket replacement stool gas cylinder (same procedure as a standard gas cylinder), but please feel free to contact us with any issues or questions.

Excellent Quality! I was also able to replace the old Gas Cylinder for the new one with one issues. Fit perfectly.

Works as a replacement for the aeron stool. Note, the original footrest for the stool will sit lower after replacement as there is no place for it to rest with this replacement cylinder. A pipe fitting or some kind of other fitting can be mcguyvered on to raise the footrest to the original height.
