## Questions & Answers

**Q: Does it work with Davis Lucid 20-ch--seat?**
A: Seems to work on most standard office chairs

**Q: Work with herman miller mirra chair?**
A: I don't know about that chair.  But it fit in the one I have.  Check the requirements of the gas lift and see if your chair meets them.   To me as long as your chair is a standard chair and the dimensions are the same, it should fit. 

How to make sure the gas lift cylinder fits your office chair?

Check the outer and inner diameter of your broken gas lift cylinder. This replacement part fits the one with an outer diameter of 2" and inner diameter of 1.1".

**Q: Can it fit an evoko gaming chair?**
A: I have used these on a few different chairs. I haven’t had a problem yet, these gas lifts seems to be pretty universal. Worst case is you take it back if it doesn’t fit.

**Q: Will this work with a Noble Chairs Chair?**
A: It worked on the one Noble chair that I have.Most of them are universal sizes, I don’t think it’s a big problem

### ⭐⭐⭐⭐⭐ Great replacement for my office chair
*by T***E on January 5, 2026*

My office chair cylinder gas lift raised too low at maximum. This replacement is perfect fit, and added inches needed for comfortable sitting at my desk. Generic, but good quality, working well so far.

### ⭐⭐⭐⭐⭐ A little work removing the old one but installation was a breeze!
*by C***R on January 24, 2026*

It was a bit of work to get the old one out but seconds to install the new one. It works great. Highly recommended!

### ⭐⭐⭐⭐⭐ so far so good. Fixed my chair. SEE INSTALLATION NOTE.
*by S***Y on October 29, 2025*

Well, it has been a few months and it is still working. Hopefully it will not fail like the last brand I bought after less than a year. NOTE ON INSTALLATION: Besides the fact it takes some strength to get the old out on, You MUST insure that it will not SLIDE up too far into the chair mechanism where the lever controls the height. ALL the office chairs seem to have this problem - it relies on a extremely close tolerance between the cylinder case and the chair holder. If it goes too far, it his the lever mechanism and will not work. AND that is even if your chair has an adjustment for that. Two of my chairs over the years have failed the way - the cylinder either quickly or eventually slides too far and stops work. So you have to figure out a solution to keep that from happening. I normally wrap the cylinder with a very thing layer like paper to keep it from going too far - of course it has to get close to the lever or you can't adjust either. A bit tricky - but due to the inherent design of all these chairs. Most people do not realize this and trash the chairs and get another.
