Office Chair Cylinder Replacement,Heavy-Duty Gas Lift Cylinder Fits Most Chairs,Highest End Class 4 Hydraulic Pneumatic Piston, Universal Size

Fit my chair, very secure and sturdy, the height was better than the gas cylinder that came with the chair. Take a look at the pictures included in the project description, install takes no time, just make sure you have a pipe wrench so you can unscrew you’re existing cylinder

Easy replacement after watching a couple of YouTube videos. This cylinder works great. It’s a bit longer than my old one and not as tapered at the end, so it sits higher in the base. That works great for me, as I wished my old chair would raise up higher and now it does.

This replacement cylinder is a beast—strong, sturdy, and a great value for the price. It was easy to install and instantly made my chair feel more solid and secure. The product claims to hold up to 1000 pounds, and it really does feel that strong. No wobble, no slow sinking over time like my old one. My wife comes into my office and i'm not worried to have her hop onto my lap.That said, I made the mistake of not measuring beforehand. I was using this on a Lazyboy executive chair, and the new lift was taller than expected. Now my knees bump into the underside of the desk, which was on me for not double-checking specs. I’ve since ordered a shorter one, but I’m saving this for another chair because the quality is excellent.If you need a tall, heavy-duty gas lift and have the space for it, this is a solid choice. Just be sure to measure your setup first!

The piston was not functioning and the chair was too low for my liking. My wife gifted it to me for Christmas. I wasn’t fond of it, but I hoped to get a new chair. At 400 lbs, my options were limited. However, this new piston truly amazed me. It operates wonderfully and was simple to install. I’m very happy now.

I got this to replace a faulty cylinder on a Staples mesh office chair. The old cylinder would weep down over the course of about 20 minutes, forcing me to raise myself back up many times per day. I considered getting a new office chair, but aside from the faulty cylinder, this chair is still in great condition and is very comfortable.At first I ordered one that was too tall. It wouldn't let me adjust the chair so that my feet would touch the floor. So I bought this one instead. This one is a bit taller than the original cylinder, but I never needed the chair to be really low so that's fine. This one does allow the chair to be adjusted much taller than the old cylinder. The old one needed to be all the way up for the chair to be at a comfortable height and with this one the best height is about halfway up which is great!Since I was going to be performing surgery on my chair, I also ordered a set of polyurethane double wheels for it and I love them too! I will never use plastic wheels on an office chair anymore. These poly wheels are super nice.Overall, I turned my mediocre but comfortable office chair into a super-nice, smooth, adjustable chair that holds its height. So far I am very happy. Will it last? Time will tell. I expect run-of-the-mill chair cylinders probably last about three or four years, but my Herman Miller Aeron cylinder is probably 20 years old and still works fine.If your office chair cylinder is failing and you like your chair otherwise, then get this one. You won't be disappointed!!

I have a four year old Staples Whitcomb big & tall office chair. Still in great condition and very comfy. However, the last three months after I have sat in it for a while it lowers itself a bit, then a bit more, until it bottoms out. I can raise it again, but later (same day, next day), it will start lower itself again. So a new gas lift cylinder was needed. Apparently they are somewhat generic, with a 2" diameter bottom and 1.1" diameter top. This was heavy duty, so I ordered it. The hardest part of installation was removing the old cylinder. It required some coaxing and WD-40 to get it out. Then putting in the new one was super easy. It works great, and I gained an additional 2-3" in height compared to the original cylinder.Thank you for reading.

My chairs gas cylinder wouldnt hold the seat up if anyone sat on it. I tried a few "fixes" as I mainly wanted it at max height, which was already too low for me. My main fix was duct tape as it was suggested by some diy cylinder fix. This eventually stopped working.Getting my old cylinder off was EXTREMELY difficult. Replacing it with this one was extremely easy!! Just plop it in the old base, set the chair onto this new HOSALI gas cylinder and it was immediately good to go, sat perfectly in the based and tightly into the mounting hole nice and firmly, no wiggle.The chair now goes up BEYOND a point that even I, 6'0 with long lets, needs but I'm glad I bought this height for my chair in case I do ever need it higher. It also feels way smoother than the old cylinder when rotating in the chair. It glides very easily but stays where I want it.I am truly shocked that this replacement is better than any of the dozens and dozens of computer chairs I've used all my life. It feels luxurious, which feels strange to say about something so mundane!I'm planning on replacing the chair soon as its not very comfortable to begin with, but I know I'm keeping this cylinder for my next chair and not even installing the base model! It really is THAT much better.
