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

I have a nice "Captain America" chair. The hydraulic pole began to slip. I found this and used a YouTube video to learn how to do it. It's super simple. I got my hammer to knock out the old pole and then just pulled out the pole. The new pole slides in easily. You sit on the chair it is set in place.I waited 2 months after ordering to make sure it continued to work. I have found zero slippage. It continues to hold strong and am very happy with the purchase. It's a great way to save a quality chair.

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.

A good shock to be sure. It extends - a lot. In fact I was stupid and bought a unit that was too tall for me. My bad.This is a solid unit and after removing the outer decorative casing I was able to fit it into my Serta office chair base without issue and it has been working great for a couple of months now.That all said, because I got a unit that is too tall the shock is always 100% compressed so I cannot attest to the longevity.We did fully extend the shock and I put well over 400 pounds of weight on it - roughly - to see how it would hold and it did not have a problem.It came with everything needed to swap a shock including gloves. Yeah, the old ones are usually greasy leaking messes so have some paper towels or a washable rag(s) handy before doing this.I will buy from this manufacturer again.

This cylinder is great. It is easy to install and works in my chair which did not come from the same company (sometimes things do not fit other companies/brands of parts). However, it is really tall. I sit at a normal size desk with a standing desk set up on top of it, and I was just an inch or so too low with my old cylinder. When I installed this one, I ended up being an inch or so too high and had to raise the standing desk to it's first height to be able to fit. So just make sure your measurements are correct for how high you want to be.

Actually, the installation wasn't difficuilt; the difficulty was in removing the old part. It fought hard but I perservered. I suggest you watch a number of different YouTube videos; some are better than others.

Had a gaming chair that needed a new gas cylinder in lieu of buying a new chair. This cylinder was perfect and nicely priced to boot.

Good quality and fit. The video accompanying the item on Amazon makes installation look easy. I had to use heat, penatrating oil, and a steel mallet to get the original piston released from my office chair on both ends. In my case it seemed the original piston was interference fitted. But after some aggression and a few choice words, I got it off! The new piston fit nicely, only needing a few gentler whacks with a rubber mallet to get it properly seated on both ends. All feels good now, and the lift feels sturdy.

I ordered this gas cylinder after searching for the part using the chair's model numberthe gas cylinder fits in the chair, but it has a different adjustment mechanism, a top level button, instead of a cable that comes in from the side.the chair is usable, but the normal adjustment lever doesn't workdespite searching for a replacement part using the chair model number, the result of the search was not an exact match

fácil de usar buena calidad

Le quedó excelente a mi silla, y un poco más alta como quería

Je l'ai commandé, par ce qu'il avait les dimensions que j'ai mesurés sur l'ancien. Mais finalement j'aurais été mieux de commander un plus long.Mis a jour de l'évaluation: Après seulement 3 mois, le vérin ne garde plus ça position.

Es muy corto, casi no sube nada y eso lo hace incomodo

Simple and sturdy as advertised in the product description. I am happy with the standard minimum height this product providers, hoping this last 1 year.
