## Description

desertcart.com: Omyoffice 5.5 Inch Office Chair Gas Lift Cylinder Replacement, Black | Heavy Duty 1000 lbs Hydraulic Pneumatic Piston, Universal Fit Most Office, Desk, Gaming Chairs, Fix Sinking : Office Products

Review: Replacement part - Perfect replacement part for our office chair. Fit great and was easy to install. Chair works great now.
Review: So far so good - Item works as intended. I saw some comments complaining about the height, but the dimensions are clearly stated on the front page…. So make sure you are aware that the baseline height may be higher than what you have now. The most painful thing was getting the old cylinder off. Watched a lot of videos that seemed to only apply to chairs with light to no use as none of it worked for me. Many hours of thumping, cursing, and self reflection to get my old one off. God speed.

## 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

### ⭐⭐⭐⭐⭐ Easy to install. Quality product. Taking cylinder diameter mesurement was not needed.
*by P***O on February 17, 2026*

I found this product because my office desk task chair recently experienced a failed lift cylinder. I honestly wasn't sure if this replacement would fit or not. After reading the reviews, I decided to take a chance and order. I watched a few youtube videos before hand to see what I was up against. Basically there's very few steps involved to extract the old cylinder, then do the same for the new cylinder. In every video you see someone whacking the base plate of the chair that holds the cylinder. I used a rubber mallet instead of a standard nail hammer. Some reviews recommend using a pipe wrench. I do not own a pipe wrench and I don't understand why you'd even need one for cylinder removal and install. After several attempts with my mallet, I could not get the old cylinder to pop out. Then I just used more muscle, and then BAM!, the old one popped out. I couldn't believe how easy this was. You just have to hit harder if the old cylinder doesn't pop out on the first try. You do the same for the bottom portion where the cylinder is pressed into the chair's wheel (spider shape) mount, also easy. Then you remove the top cap of the new cylinder and kind of lightly tap the new cylinder into place. I used a block of wood over the butt end of the bottom of the cylinder to hit, so I wouldn't damage the new cylinder. It doesn't take as much force pressing/hitting the new cylinder in place. I think body weight and gravity will help seat the new cylinder over time. Super easy install. I'll also note that I decided to upgrade and get the tallest cylinder (5.5"). I think I may have doubled the height at it's highest point compared to how my chair was bought when new. The lowest point is now just below where my old chair use to rest at it's highest. So keep this in mind. You may need to consider whether or not your chair can still be stowed at your desk if your chair has armrests. A taller cylinder might prevent the chair from sliding under your desk if the armrests end up hitting the desktop. My chair still fits, but only if I lower the chair to it's lowest setting. I actually prefer the taller cylinder since I have long legs. I also like that it's almost stool height now, for when I'm playing guitar etc.
