Fits perfectly!

I would like to preface this by saying I am fairly strong. Like I have picked up a full size bar fridge by myself and lifted it onto a counter. I do not normally have trouble with things like this but when other reviews say the hardest part of replacing this part is getting the old canister out, believe them! So my chair had been randomly sinking for a few months, forcing me to stop and readjust it or type with my shoulders hunched up to my ears. Eventually it just would not stay in place and since I really like my chair and it wasn’t cheap, I decided to try and fix it. Read the reviews, compared prices, and settled on this one. The new cylinder arrived quickly and I watched a video on how to replace it. Very simple process. Great! I will be sitting like a proper human in no time. Needed a pipe wrench to get the old cylinder out of the chair, which was stiff but not bad, but when I got to the base it absolutely would. not. come. off. Wailing on it with a mallet, then a hammer, soaking in WD40 overnight, taking the wheels off so the cylinder could touch the floor and standing - then jumping - on the base arms. Nothing worked. The nice new cylinder sat in its box while my chair was in pieces and the smell of WD40 lingered everywhere. After 2 days working from a kitchen chair I finally gave up and ordered a new chair base too. Once it arrived this cylinder was super easy to install and it fit perfectly. It took about a minute to reassemble my chair and the hardest part was getting the wheels into the new base as they kept trying to slide off in any direction but down. That was a few months ago and no issues at all with my chair since then. I don’t randomly start sinking in the middle of video calls anymore. Even with buying the base on top of the cylinder it was still cheaper than a new chair. So overall good purchase but be prepared you may need a sledgehammer to get the old one out. TLDR: product is great, installation is easy. Disassembly of previous part not so much.

Can’t say enough about this great well made piece. Easy to install. I didn’t want to part with my chair. As it’s comfortable and made well. I’ve had it for decades. So finding this replacement gas replacement part was a game changer. I’d highly recommend this item if you should be in the market for a new replacement part.

Very well made. Super sturdy.
