I ordered this as a replacement for my hydrolic lift that could not keep its height. I got this and couldnt be happier with the allen wrench and removial kit i was able to get off the old cylinder off easy then i replaced this with no added problems now my chair actually lift higher then before.

Bought this to fix my aging HM Aeron chair. Almost paid for a company $160 to fix, until I found this on Amazon. The hardest part of the whole install was hitting the base of the chair to separate the wheels from the cylinder. Once that was done, it literally took me 10 mins to replace.

Excellent Product! Easy instructions, very clear. I had no issues with my replacement, and took maybe 15 minutes total. Make sure you tighten the collar down as tight as possible when removing the old cylinder. Once you get it tight enough, works like a charm. Would definitely recommend, and would buy again if I need to replace a cylinder. Gloves definitely came in handy as well.

The tool to remove the cylinder from the seat frame works great. It took less than 10 minutes to remove the cylinder from the seat frame. It took a little longer to remove the cylinder from the chair base. Installation of the new cylinder is quick and easy. The cylinder works great. It holds the adjusted height, unlike the old one. Very satisfied.
