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

Seems to work great. My chair is relatively new, but it would slowly lower throughout the day, got to be more and more annoying. This did the job. Super easy fix, just the old one can stick and it take some extra pounding to get it off. Very few tools needed.

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.

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!

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.

This was great. Saved me from having to buy a new chair. I like my chair and this allowed me to keep it. It is like other reviewers said, it is tall and the lower setting is still very high, but for my desk and for me it works just fine. I hope it lasts.

Pain to get the old one out but simple to just pop this new one in place. Hubby was impressed I fixed his sinking chair without telling him. It’s the little things!

Hey this was a good fix!A+A+A+

I recently assembled an executive chair I ordered (thru Staples). When I finished the assembly and sat down for the first time I was disappointed that it was too low for me to comfortably use at my desk. I was very pleased to learn that I could replace the cylinder that raises and lowers the seat and ordered this unit. Removing the existing cylinder was more challenging that I expected (it took numerous hammer blows!) but this new unit dropped into place easily. My chair now easily raises to the exact height I needed (and higher if desired!). The manufacturing quality of the cylinder seems very high and the polished chrome finish looks great. Highly recommend!
