Omyoffice Office Chair Cylinder Replacement,Heavy-Duty Highest End Class 4 Hydraulic Pneumatic Piston, Universal Size Fits Most Chairs

This did the trick , my old one that this replaced would sink almost immediately, I’m a big guy 6’2” and just about 300lbs, This cylinder is heavy duty, it’s supportive and goes taller than my old one. Highly recommend it!

This cartridge was a perfect fit for my Staples brand office chair. When you are preparing to remove the old one, prepare for some muscle work! I used a vise grip, pipe wrench, and a hammer. The big pipe wrench gave me the grip and leverage I needed to twist the cartridge out of the base. The wrench was too big to grab the chrome tip near the seat, so I used a vise grip and beat it with a hammer to remove it. Very satisfying! The new cartridge just drops in place. When you place the seat on top and sit down, the installation is done! My chair is like new again.

I bought 2 new matching chairs for craft room. They didn’t rise high enough for my craft table. Purchased 2 of these and they worked perfectly!!! Great purchase. Definitely recommend. Easy install!

I used this particular cylinder to replace the leaking one on my 6 year old Serta "Big & Tall' office chair. Removing the old cylinder from the chair base was the hardest part, but after reinstallation it worked perfectly... almost!The only downside is that the chair sits almost as tall as it did on the new lowest setting as it did on the medium/high setting on the original. That being said, i cannot lower it to push it under my desk anymore, and fully extended, my feet are easily off the ground (im 6'2")Not a huge downfall, but be sure to measure your original cylinder size before ordering a new one if you want to retain the original height and settings.That being said, it really is a good, high quality piece that fit the base of my chair perfectly. I just wish it sat a little lower, but i can live with it versus replacing my chair completely.

So far so good on my Steelcase TS30832 a type of Turnstone model. Easy install. Tap out the base part of it. Then you might need a pipe wrench to turn it from high under the chair. It doesn’t shoot unscrew but the pipe wrench will break it loose.I have to pull the chair up to raise it. It doesn’t shoot up on its own.Quiet operation.

I came across a Herman Miller Aeron at a used furniture store for less than $100, and since I had been considering getting one, and a good refurbished one still costs $400-$600, I figured it was worth a show fixing it up. The cylinder in the air didn't work, and would slowly settle down to the bottom with any weight on it, so I bought the chair, this cylinder, and a new set of casters all in for less than $150.The hardest part about the whole thing was getting the old cylinder off of the chair (I ended up using a hammer to loosen it after getting nowhere with a pipe wrench). From there, it just took a minute to get the new cylinder in and then get the height adjustment lever properly adjusted.I can't speak to the long term use of this cylinder yet, but so far, about 2 months in, I haven't had any issues.

Worked great as a replacement for the gas unit on my chair. Super easy to install.

Read this. Most people would go out and buy a new chair . This was a very cost effective method to fix my current chair that was in great condition except for the lift. That being said, despite me premeasuring, this size is very tall for a home desk. The lowest setting is almost the height of my old shock, therefore I recommend you measure your old one. I can no longer roll my chair under my desk. I would return it and go through the hassle, but it's hardly worth it. As far as quality, it's good quality. And, I replaced my old one in less than one minute by following the video tutorials.
