## 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

## Customer Reviews

### ⭐⭐⭐⭐⭐ The Perfect Fit
*by J***E on September 13, 2025*

Excellent. This 5" office chair hydraulic worked out just right. The lowest level was more than adequate. The highest level actually allowed an average person to just touch the floor with the tips of your shoes. It made a world of difference from the 23" hydraulic the chair initially came with for the height adjustable table. My wife is very pleased with her chair now.

### ⭐⭐⭐⭐⭐ Great product.. can be challenging to install
*by J***R on August 7, 2025*

Exactly as advertised, it fit perfectly and I love the chair again! one thing to keep in mind: getting the old cylinder out can be challenging. I used a rubber mallet and a fair number of hits before the legs popped off. Other than that, it was quick and easy!

### ⭐⭐⭐⭐⭐ I had to alter the cylinder to make it work with my chair
*by S***N on July 31, 2025*

I own a Steelcase office chair. Its gas lift cylinder wasn’t tall enough for my studio and it started to sag after a few hours of sitting. Along comes this OmyOffice 5 1/2” gas lift cylinder. First of all it took an act of congress to get my current cylinder uninstalled. You’ll need a large pipe wrench. I also tried using a large rubber mallet. It took me a while. Once I got the new one installed I could position the chair much higher than before, however when I sat down the chair lowered all the say to the bottom. I thought the new cylinder was defective. Turns out that the mechanism that depressed the button on the top of the cylinder on my chair had a screw. The original button on the original cylinder was kind of recessed. So with the new cylinder the button was pressed regardless of what the chair lever was doing. I ended up having to cut some of the plastic button off on the new cylinder, thus shortening the height of the button. That fixed the problem and the cylinder works perfectly. I suspect that is not common to all the other chairs out there, but if your chair won’t stay up that might be why. It arrived quickly and I’d buy it again.
