Review: ease of use - Easy to install and works great
Review: Great quality - When adding a new base to my chair so I could have wheels, the original gas canister was STUCK in the old base. I tried my best but could not get it out, and the manufacturer was useless when I asked for some sort of help (since they sent the wrong chair as I ordered one with wheels and they sent one without). I eventually gave up and ordered this gas lift and it fit perfectly, and lifted the chair a little higher than before. That's a good thing, since I now no longer sit so low at my desk! I don't even have to lift the chair at all, but I did lift it all the way to test it out, and had three people sitting on top of each other in the chair (over 550lbs combined) and it still felt perfectly sturdy). Definitely worth the purchase and not bad price wise.

## 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
