Crandall Office Furniture’s Herman Miller Aeron aftermarket 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 gas cylinder today.

Our Herman Miller Herman Miller Aeron gas cylinders are made to fit all Herman Miller Aeron chairs manufactured before 06-26-2013.

If your Aeron chair was manufactured after 06-26-2013, it uses our side activated style cylinder, which can be found here.
