MingYi.office Gas Cylinder Heavy Duty for Herman Miller Classic Aeron Chair as Replacement

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.

Unfortunately this cyliner only worked for a few months before it started to leak...

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.

Solid gas cilinder for my areon classic chair. This seller was very attent and nice, they contacted me right after my purchase to ensure me that my package would be delivered on time. And it did, it come three days earlier. my previous gas cilinder broke and so I could lift my chair of the base, because the outer shell of the old cilinder stayed attached to my chairs base. this is unusual but it happens sometimes. At first I thought that this 20 cm long pipe was where the new cilinder would go in, but I was wrong. It had to come off and I had a really hard time getting it off, nothing worked, pliers and wrenches got wrecked in the process. eventually I took the seat off and removed the the cap and put a deep socket on the cilinder and beat it out with a small sledgehammer. After that everything was easy and my chair sits great again. I must add that it would be good to know that after installing, the seller recommended adjusting the pump screws on the side of the chair. In my case this was not necessary, my chair was lowering when sad on it but I needed to adjust the screw above the cilinder. Happy customer, 5 out of 5.

Perfect fit for aeron classic

Muy buen pistón. Quedó perfecto en la silla, sube y baja sin problema. Se mantiene a la altura, prácticamente como si la silla estuviera nueva. La verdad es que reviví una super silla. La instalación requiere mucha fuerza para quitar el pistón original, sobre todo si es que tiene muchos años como en mi silla que tenía más de 15 años con el pistón original. Colocar el pistón es bien fácil y solo bastaría ajustar el nivel del botón para habilitar la palanca para subir y bajar. Nada que no puedas hacer, hay videos en YouTube que te guían para hacer el cambio
