## 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
