Crandall Office Furniture’s Herman Miller Aeron aftermarket heavy duty gas cylinders have been constructed to meet original OEM chair specifications and are built to last.
All of our heavy duty gas cylinders are rated Class 4 (Class 4 is the highest class of chair cylinder available).
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 gas cylinder today.
Our Herman Miller Herman Miller Aeron Classic gas cylinders are made to fit all Herman Miller Aeron Classic chairs manufactured before 06-26-2013.
This gas cylinder will not work with the newer remastered style Aeron chair.
If your Aeron Classic chair was manufactured after 06-26-2013, it uses our side activated style cylinder, which can be found here.
