Omyoffice Office Chair Gas Lift Cylinder - Replacement Parts, Universal Size, Heavy Duty Hydraulic/Pneumatic Piston, Black - Alloy Steel

not good just worked 2 months and it fisssssss , my old worked 3 years

Stopped working within a month of using it. Plastic part used inside started to come out in powered form.

Works fine

Putting this on a chair is the biggest hassle. However the item itself is flawless.

Broke in 2 months. Worst product, wasted money.

Definitely looks sturdy than the one that I had. So far good and hoping it lasts for atleast 3 yrs unlike last product (different brand) which lasted only 2yrs..

Sturdy and stable. Not loosing the chair height frequently

Poor quality

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.

Broke first day , bad quality

Excelente producto

Oh wow, what a long cylinder this thing has! I'm six feet tall and about 350 lbs, and this can more than adequately handle my leg length and weight. Effortless to install. Really pleased. I'll be buying another one for my home office chair too.
