Review: Office Chair Savior – DOZYANT Gas Lift Cylinder! - When the gas lift on my office chair started giving out, I was on the brink of buying a whole new chair. That’s when I stumbled upon the DOZYANT Gas Lift Cylinder, and I decided to give it a shot. This decision turned out to be a game changer! The installation process was incredibly easy, and it fit my executive chair like a glove, thanks to its universal size design. It's evident that this cylinder is built to last, supporting up to 450 lbs with a seamless and smooth operation, making it feel like I've got a brand new chair. The hydraulic pneumatic shock piston operates flawlessly, providing the perfect amount of lift and stability. What impressed me the most is how it has transformed my seating experience at work, ensuring comfort throughout my long hours at the desk.

The DOZYANT Gas Lift Cylinder is a high-quality, durable solution that I would highly recommend to anyone facing similar chair woes. It’s truly a top-notch product and the highest end of its class!
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.
