Review: Harder to compress than the old one, but works just fine. - Little harder to adjust up and down because of the pressure of the cylinder, but, so far so good. Much cheaper than buying a new chair and took all but 10 minutes to install with a couple clothes and a small hammer to nudge the old one out of the chair seat. Ill update if it goes out within a year.

## Questions & Answers

**Q: Does this shock sit you up higher than most chairs**
A: "Than most chairs?"  NO.  There is no "most chairs". This is 5" extension model (really 4 1/2) which is middle of the 3 standard extension.  You need to measure the total compression, lowest to highest, of your existing chair and get the model that matches it (or changes it if you want that).

**Q: Is the weight capacity rating correct (1,000 lbs.)? this is the only i've seen with that rating at comparable prices. thanks.**
A: I know it is much higher than any of the other chairs I have had it also adjusts to much higher height if need be. I have not tested to 1000 lbs but it is very sturdy even if using all day, everyday.

**Q: I have an effezeta executive office leather chair made in Italy. Will this gas cylinder fit?**
A: You would need to find out if your chairs cylinder is replaceable and if it uses the same size cylinder.  The cylinders work great, I have replaced the cylinder in two chairs and they work great.

**Q: What is the length of the gas lift cylinder?**
A: 10", 15" extended. So 5" of adjustable height.

### ⭐⭐⭐⭐⭐ Functional and reasonably priced

Easy to install. Does the job. Will see how long it lasts. Helped save me a few $$ for sure on an existing office chair that needed a new cylinder but the rest of the frame was fine.
