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

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!!

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!

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.

im 3hundred plus pounds and this was a good replacement for our chair.

Le devolvió la vida a mi silla. Instalación rápida, aguanta buen peso y se siente resistente. Perfecto para evitar comprar silla nueva.

Had to go onto You Tube to get instruction on removing chairs old hydraulic cylinder. Be advised if you remove cylinder the way I was forced to the old part will be unusable. The way I look at this conundrum is it’s already broke so it can’t be fixed.Take a regular ol” every day hammer and turn chair on side. Look at bottom of cylinder protruding out of the center of the base with wheels on. Hit the cylinder as hard as you can and drive it out. Chair will now be seat section and wheeled base. Now use the lever that is used to raise and lower sear and get the cylinder to fully extend. If that doesn’t work pull on cylinder and make it extend. Where cylinder enters chair base apply WD40 or a light oil at the area where the shaft enters seat base. GET PIPE WRENCH and grasp the shiny metal shaft. Turn the shaft, it will take a lot of pressure to get it to turn, Persevere! It will eventuallyStart to turn, add more oil if need be. Once loosened it will be easier to turn, just keep turning it till it comes out. Then install large black end into middle of chair base. Lift seat section up and slide shaft into bottom of seat assembly. Remember to slide the black plastic cylinders onto shaft before placing shaft in chair base. Now you have new office desk chair. Good luck I love this fix, as where can you get a desk chair for less than $25.

Its very stable and the price is right. I would absolutely buy again, but hopefully not too soon.

In some cases I suppose you could pop out the old one and place this one right in in 30 minutes and it would work. If your old gas cylinder is welded (mine was, from walmart years ago) be prepared to be completely sol and I would just ship it back and get a refund right then.After watching many videos and still struggling to get the old canister out (1 hr in) I finally realized it was welded. Didn't want to cut/grind the only bc I'd have no fallback option, but figured I had to. 2-3 hrs in I realized I may have actually been able to keep the old part if cutting did not work. Also this thing came with 3-4 nuts in it but if its anything other than a quick install the nuts are guaranteed to fall out of place and you'll never be able to websearch how they're supposed to be in.Hr 4 was when I finally grinded it small enough to fit and had safety concerns but tried anyways. And hr 5 was when it broke anyways and I decided to just go buy a new one which was what I had tried to avoid doing in the first place.This could have been averted entirely with even just 1 piece of paper with the list of parts in the box and showing the inside of the canister. But I guess that is one penny too many and every corner must be cut. The old chair manual was inadequate, and any paper for this was non-existent, and I went from poor chair to no chair, and lost ~4 hrs of time trying to make this work.0/5 stars if I could.
