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.

I wanted to convert my Steelcase Leap V2 to a stool but the conversion kit they sell are $120+. I took my chair apart and measured the hydraulic and this one seemed to fit so I ordered it. Well, what do you know, this thing fits perfectly! But to make the height adjustment work, I had to cut the tip of the orange plastic part flush with the casing. This allowed me to save so much money.

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.

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

Loved the 8 inch travel and sturdy, however I need to buy a cylinder removal tool (also puchased on Amazon: https://www.amazon.com/dp/B0CC3TYZDN?psc=1&ref=ppx_yo2ov_dt_b_product_details) to remove the old cylinder. Now my 17 year old stool is like new.Once the old cylinder was removed installing this new cylinder was easy-peasy!

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.

Was delivered early January 2024. On February 7 2025 the seal broke and it no longer works correctly. A one year life cycle is not very long.

Perfect and tall! Wow! Haha!!! This is exactly what I needed. I needed a drafting chair, but loved my old Serta, and didn't want to part from it. So, why not? This turned my old comfy chair into a tall comfy chair.Installation was super easy. Taking out the old piston wasn't that difficult, either. (There's plenty of instruction videos out there. A pipe wrench came in handy for disassembly.)

The gas lift cylinder is just as described in the listing and arrived a week before the predicted date.
