Lesson to learn
I am updating this as I had left a scathing review. After about three weeks it seemed like it was collapsing when someone say in it. Ends up I had to tweak the height adjuster screw just a bit out and it is all good again. Right now would buy again

Heavy Duty It Is NOT! Cheap and Nasty and Will Not Last
On arrival this gas cylinder looked excellent. Well packaged and arrived quickly. Instructions were almost non-existent - "go find a YouTube video...." - and no mention of the tools you would need (a pipe wrench and a solid, non-damaging mallet). However, I overcame these obstacles quite easily and managed to get it swapped over. My original chair gas cylinder for my Herman Miller Classic Aeron Chair has lasted from 2004 until 2023 and took a bit of effort to remove, but I got it removed and replaced it with this and made the necessary adjustments so it worked perfectly - hooray! After just 2 days I noticed the chair felt a little wobbly from side to side and front to back. Everytime I move in the chair it feels more unstable. The photo shows where the top part of the wider section of the cylinder seems to be coming away from the main section, and this is what is causing the wobbling. The video shows the actual extent of the problem, with the top part rocking from side to side, and this is getting worse every day and I'm sure will eventually break away completely. I'll be returning this and buying something else.

Excellent aftermarket cylinder for Aeron
This China aftermarket gas cylinder for Aeron was EASY to install, fit perfectly and worked immediately upon installation. I DID have an extremely difficult time removing the original HM cylinder from the chair. It had been there for decades. The online videos made the removal look way easier than it was. It took a number of overnight WD-40 soaking, the biggest heaviest pipe wrench I could get and a LOT of aggression in numerous sessions to incrementally move that old cylinder a few millimeters at a time. When it finally came out, the new one slipped in like a charm, what a surprise, it was a good quality purchase. The chair being an original HM Aeron would cost close to $1K to replace...and was a Great Incentive to put up with the hassle.
