Review: Easy, solid replacement - Replaced a gaming chair piston and was much easier than expected and works better than when new
Review: Great! - I had an office chair from OfficeMax that was slowly bleeding down. This part fixed it. I did have to resort to some tools many homeowners won’t have. I had to use a big pipe wrench to get the top loose from the seat mount and a big hammer to drive the cylinder out of the base. Price is great! High quality! Has a huge lift, like feet off the floor height! Immediate shipping!

**Q: Whats the exact size of the item?**
A: By Amazoncustomers on May 26, 2021

**Q: Is it quiet? Or do you make a sudden noise when you move around?**
A: By Amazoncustomers on May 26, 2021

**Q: Work with herman miller mirra chair?**
A: No, this type of gas cylinder will not work with a great deal of Herman Miller chairs.  This is because most chairs that Herman Miller has manufactured over the last 20-25 years use a cable to actuate the gas cylinder.  Mirra is one of these chairs.  It has a special mechanism on top of the gas cylinder for attaching the cable assembly.  This gas cylinder won't work for Mirra.

### ⭐⭐⭐⭐⭐ Great replacement to keep your favorite chair
*by D***X on November 5, 2023*

Bought replacement to fix favorite realspace desney chair I had bought to work from home during pandemic. I am a big guy 6'3 375, and the cylinder for the chair gave out, it had been out a while. Decided to take a look at replacement cylinder to fix rather than replace favorite chair. First of all the hardest part about replacing cylinder was removal of cylinder. The following is soe advise to do so. You will need a rubber mallet or hammer. WD-40 and a pipe wrench. 1. Spray wd-40 around base of chair where cylinder connects to base. let sit overnight if possible. 2. To remove cylinder from bottom of chair use pipe wrench grip firmly a couple of twists later top part of cylinder is removed from chair. 3. turn base over use square wooden block over the base part of the cylinder sticking out the bottom of base. And hammer out. 4. After old cylinder is out line up new cylinder remove cover at top before sliding into the bottom of seat Just some advice to help anyone out there, Like i said I am a buy guy pretty sure the old cylinder was pretty in there. New cylinder appears to be sturdier and higher for sure. Chair is comfortably at typing height on kitchen table. Would definitely buy again.
