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 side activated style gas cylinder, manufactured after 6/26/13.
This gas cylinder will not work with the newer remastered style Aeron chair.
If your Aeron Classic chair was manufactured before 06-26-2013, it uses our top activated style stool cylinder, which can be found here.

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.
Product Specifications:
- Overall Length / Maximum Extension: 21.75″
- Overall Length / Minimum Extension: 14.50″
- Amount of adjustment: 7.25″
- Only Fits Herman Miller Aeron Chairs using the newer side activated style gas cylinder, manufactured after 6/26/13
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.

I used this in an Allsteel Acuity chair. Not only did it give enough height for my extra tall desk, it also goes to nearly the same bottom. It fit perfect. Thanks Crandall!

Your website and videos incorrectly mention this as being compatible with the new Aerons

Hi there – We apologize, we thought we had made it pretty clear this was only for the Aeron Classic chair, but have made some additional edits to the page to make it more clear. We appreciate the feedback 🙂

The part works well and your video on swapping the cylinder gave me the confidence to fix it.
Philippe Tremblay –
This gas cylinder is heads and shoulders above what you can buy from other websites.
The video instructions were incredibly clear, and I noticed the difference in quality immediately after installing it.
Thank you!
