Review: ease of use - Easy to install and works great
Review: Great quality - When adding a new base to my chair so I could have wheels, the original gas canister was STUCK in the old base. I tried my best but could not get it out, and the manufacturer was useless when I asked for some sort of help (since they sent the wrong chair as I ordered one with wheels and they sent one without). I eventually gave up and ordered this gas lift and it fit perfectly, and lifted the chair a little higher than before. That's a good thing, since I now no longer sit so low at my desk! I don't even have to lift the chair at all, but I did lift it all the way to test it out, and had three people sitting on top of each other in the chair (over 550lbs combined) and it still felt perfectly sturdy). Definitely worth the purchase and not bad price wise.

### ⭐⭐⭐⭐⭐ so far so good. Fixed my chair. SEE INSTALLATION NOTE.
*by S***Y on October 29, 2025*

Well, it has been a few months and it is still working. Hopefully it will not fail like the last brand I bought after less than a year. NOTE ON INSTALLATION: Besides the fact it takes some strength to get the old out on, You MUST insure that it will not SLIDE up too far into the chair mechanism where the lever controls the height. ALL the office chairs seem to have this problem - it relies on a extremely close tolerance between the cylinder case and the chair holder. If it goes too far, it his the lever mechanism and will not work. AND that is even if your chair has an adjustment for that. Two of my chairs over the years have failed the way - the cylinder either quickly or eventually slides too far and stops work. So you have to figure out a solution to keep that from happening. I normally wrap the cylinder with a very thing layer like paper to keep it from going too far - of course it has to get close to the lever or you can't adjust either. A bit tricky - but due to the inherent design of all these chairs. Most people do not realize this and trash the chairs and get another.
