  • Works As Described
Size: 5.5
I got this to go with a basic gaming chair, where some of the reviews had concerns about the hydraulic lift. So to be on the "safe" side, I order this to go with the chair. Being a heavier guy (around 275#), I figured this would do well. And I have to say it does indeed. Fit well, and allowed for not only better weight, but allows me to have the chair at a higher level. ... show more

  • Very impressive!!!
Size: 5.5
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. ... show more

  • replacement cylinder
Size: 5.5
office chair needed new cylinder. Very difficult to replace, no fault of the new product, old chair and old cylinder didn't want to be separated.

  • Perfect for big and tall
Size: 5.5
I’m over 6 foot 2 inches and 400 lbs, and this is perfect. The gas cylinder my chair came with was too short for me. This goes higher than I would ever need, which I love

  • Great product HARD TO REPLACE!
Size: 5.5
I come to you from your own future to WARN you that attempting this replacement is NOT as easy as the YouTube videos make it look! It took me a variety of tools, about 3 hours and made a huge mess. Removing the old piston is VERY VERY difficult. Once I finally did get it off (it was fused on both ends - even broke a hammer and a file getting it out) the replacement product installed in 10 seconds. Happy with the final outcome but would NEVER attempt to do this again. Just buy a new chair...... seriously this was NOT fun. ... show more

  • My "Big & Tall" Chair finally works!
Size: 5.5
This cylinder is fantastic! The one that came with my extra large chair was terrible. It's highest setting was barely adequate, and would slowly sink down under my weight. I was skeptical that this cylinder would fix my chair, but did it ever! The lowest setting is comfortable for my 6'5" height, and at full extension it gets my chair high enough for a bar table (~42"). The cylinder easily counters my 370lb weight without a hint of sag. I'm very happy with this purchase. ... show more
