Tall & just what I needed
I have a secret lab titan , but it was too short for my recently installed wall mounted desk , so I got this , now my feet don’t touch the ground ( I am 6’0ft) but my body is positioned just right for my desk. Sturdy , I never feel like it’s going to break . The install was tricky but if you have a rubber mallet to remove the old piston , then you should be good to go .

Easy installation and smooth operation
Purchased a new and comfortable office chair and wanted to be able to have it rise higher. So bought this 8" cylinder to replace OEM. Worked fine and liked the pricing. Appears solidly made.

Really high
I needed a gas-filled cylinder for a chair that could go high up, as I needed one for the garage use. This one is longer in its fully compressed position compared to average cylinders, and when extended you are sitting really high up. Even at fully compressed height is high enough for me.

Failed after 2 moths of use
I've using this cylinder on my computer chair, and after only two months of non excessive use, the cylinder failed. It keeps rising on its own. This is a Herman Miller office chair, and the adjustment system on the chair appears to be working properly. I believe the pin on the cylinder that's used for the height adjustment has failed.

Perfect for raising my Aeron Chair
Pictures show the before and after maximum heights of my Aeron Chair as well as a side by side comparison of the cylinders. Very happy with the difference! I'm 6'5" 255lbs and it holds my weight easily.

Easy to install!
Great product! Took a few measurements, looked on Amazon and found this one that was even taller than my existing one that sprung a leak and broke. Feels good to know that I saved the life of my beloved shop stool. Who even knew that you could get this kind of stuff on Amazon??
