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 gas cylinders are made to fit all Herman Miller Aeron chairs using the side activated style gas cylinder, manufactured after 6/26/13.
If your Aeron 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.
- 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.
