This piston worked very well. I did have to return due to length, but at no fault to seller. I assumed the measurements and was way off. I used until replacement size was received and was very happy with the performance of this. Check the measurements, if they are appropriate this is a solid purchase. Very sturdy

I like the long travel range, but they are a bit tall for a regular office chair. The minimum height about matches the maximum height of a standard office chair cylinder. Installation is simple: remove the old cylinder and drop the new one into place. Extracting the old cylinder was a challenge: I had to turn the base on it’s side and push the old cylinder out with tools. It is a friction-only fit— no screws or twisting necessary.

My old short (normal*) cylinder started failing, and like a good American, I started shopping for a brand new chair. Since I only had 2 kidneys, I decided to simply clean the old chair, and replace the pneumatic cylinder with this one. It arrived the next day completely undamaged as they had packed it well with a protective plastic cover for the valve release button, and let me tell you guys, this was the best most satisfying upgrade to my home office setup.I was able to install it within 5 minutes and all I needed was a mallet, a punch (to push the old cylinder base out), and a pipe wrench (to twist the old piston out of the chair socket). Installing the new cylinder is a simple press fit, so place it into the base and carefully mount the chair section and enjoy your brand new throne.Amazing value. Got exactly what was advertised! Thank you!

I purchased a new office chair and height adjustable desk. Because I was in a small space I wanted the ability to move around my desk – so a put wheels on the desk, which made it taller than normal. Now my chair was too low for my desk. I ordered this adjustable gas lift so the chair would sit higher, so wrist will be parallel to the desk, and it was a game changer. The replacement gas lift helped me sit ergonomically in my workspot. Would I recommend this gas lift? Definitely.

I wanted my chair to sit a little higher so I was able to change the lift

I needed a replacement air lift cylinder for my lab stool. I ordered a cylinder (not this one) then struggled to get the old cylinder out of the chair. I applied penetrating oil and still needed a 3 foot breaker bar on the pipe wrench while standing on a 3 foot breaker bar to hold the chair from moving. The wrench put deep gouges in the old cylinder, but it came loose. The replacement turned out to be too short. It also would not seat completely, and the chair would not adjust height. I was not able to measure the cylinder while it was still in the chair and ordered the wrong cylinder. That is on me.I ordered this cylinder after I was able to measure the original. It fits, and the chair height is adjustable.Don’t believe the videos that show how easy the cylinder is to remove. More than once I thought the torque would ruin the chair.This is a good product. It went in easy. I hope I never have to replace another one of these.Update:The chair is now wobbly. The metal in the chair’s seat must have deformed when I removed the old cylinder with such force. I need a new chair.
