Crandall Office Furniture’s Herman Miller Aeron aftermarket 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 AFTER 06-26-2013.
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 cylinder, which can be found here.

I’m not mechanically inclined, so I wasn’t entirely sure I could replace the gas cylinder in my Herman Miller chair. But my old cylinder had me sitting so low to the ground that my hips and back hurt every day at quitting time. So I ordered this replacement from Crandall. Then I watched (and re-watched) Crandall Office Furniture’s video on YouTube titled, “How to Replace the Gas Cylinder on a Herman Miller Aeron Classic Chair,” which was HUGELY helpful. I can’t say it was all that easy (thank goodness for WD-40 and that 24-inch pipe wrench!), but I got the job done. And let me tell you, this cylinder fits my chair like a glove. It might keep me a little higher than the cylinder that came with my used chair, but it’s great! Thank you, Crandall Office!
