5.5 inch Office Chair Gas Lift Cylinder- Replacement Parts,Universal Size Fits Most Chairs,Heavy Duty Gas Lift Hydraulic/Pneumatic Piston (Black)

EXACTLY what I was looking for. Fits perfect, made of strong material, and the 5.5” is an extra bonus. I’m 6’2” and my feet now dangle off my chair! Would definitely recommend to those who don’t want to replace the entire chair.

This worked perfectly to restore my favorite chair. Sturdy and quiet, was easy to install and am super happy with it. Good value for the money vs buying a new chair.

I have an oversized office chair from a reputable brand, and one day the gas cylinder went kaput (it was rated for 450 lbs due to it being the Big & Tall model). Under their warranty they shipped me a new cylinder, which arrived from Canada damaged and had lost most of its pressure/resistance so you could push it all the way down just pressing with your hand. Since I had already waited almost two weeks to get my chair working again, I opted to just buy a "heavy duty" cylinder on Amazon.It was delivered to the office within 2-days and is also superior in quality and construction to my previous *two* cylinders. I love that the 5.5" option gives me a little more height (I am 6' 5" and have long legs), and it isn't even a little spongy when I sit down. Although it was a hassle to me that my best option was NOT sticking with the warranty, rather paying for the part out-of-pocket...it was cheaper than most options and performs better than the original did when it was new. For this reason, it's a 5-star product to me between the value and utility I get from it.

Bought the bigger cylinder so at its lowest point is the desired chair height and therefore acts as a solid mount. (Because I don’t need to raise the chair).

Easy 10 minute job. Check out You tube for installation tips. I used pipe wrench, hammer. and a garbage can. Stick the base upside down in the can and give the lift a whack. Done. My old base was not the exact size as the new so measure first. As a result, I am sitting higher than my old lift. I am going to give it a few days to see if that will be acceptable. As a further review. I discovered that my original unit was a smaller size at the bottom portion and that this unit did not insert fully. I had to return to get the right one.

So far so good! I just got this installed on my office chair. I knew it was going to be a bit taller than my original, but that is okay, I am 6'7" and a chair being a little taller is quite alright with me.However, it ended up being about 5 inches taller once fully extended! When I lean back in my chair MY FEET ACTUALLY DANGLE IN THE AIR!!!! I have not had this happen in quite a long time!1000% would DEFINITELY buy again!

Needed a new one and saw my old one was plastic on the 400lb + chair. This one is metal and super sturdy. Im only 200 lbs but bought a super comfy chair for bigger people and this helped with my broken one. It doesnt budge even when rage gaming rocking on chair!

The reason why I'm giving this a four-star review is because it works for about 4 to 6 months and then after that you almost certainly have to buy another one. And that's kind of the worst thing about it. However, it works very well during that time.
