DOZYANT 6" Long Stroke Office Chair Gas Lift Cylinder Replacement,Hydraulic Pneumatic Shock Piston Heavy Duty (450 lbs) for Tall Person Universal Size Fits Most Executive Chairs, Highest End Class 4

It is very good and sturdy product. Good Value for money. Fits well with my chair and able to use in different height settings. The functionality of the device is good.

Good, works as expected

Nice product

I bought this gas lift cylinder for my office chair, and it has already failed after about five months of normal use. The top of the cylinder became visibly deformed, and once that happened the chair started wobbling and felt unstable. I only use the chair for regular desk work, so there’s no reason the metal should bend or wear out this quickly. The deformation at the top made the entire chair loose and unsafe to sit on. This cylinder did not last anywhere near as long as it should have, and now I have to replace it again. Unfortunately, I cannot recommend this product due to its poor durability.

Build quality and performance are excellent. Right price also.

Perfectly fits in, no issues and one can go for it easily, it's been a month and there is no issue.. it's enough long to accomodate the height.

Yes As other review max size is not according to description only 14.5 Inch Beside this size cheating, it fulfil purpose, very smooth n easy to install

Good product but price is high

Easy installation. 50mm diameter. Worked well to replace my dxracer prince series gaming chair. This one is good for taller people.

The item is exactly as offered, and working very smoothly. It was delivered ahead of schedule. Thanks Amazon for a job very well done. Keep up the good work...

I have some very expensive office chairs, and the cylinder went bad on them. I did not want to spend several hundred dollars for a new chair and was researching replacement of the cylinder online, when I came across this excellent value and easy to replace cylinder for my chairs. Now my chairs function just like as if they were new and give all the proper support. These heavy duty cylinders work excellent because I’m a pretty big guy weighing about 300 pounds and they support my weight all day.

Recently picked up a Desky chair and have found it pretty disappointing mainly due to the very low sitting height. After doing some research I found that chair lift cylinders are pretty much standardised so figured I’d give this one a go. After some struggle removing the old one (look up a guide, you’ll need a mallet and a pipe wrench) I was able to replace it and was immediately impressed with the added height. I’m 6’5 and at full extension my feet mostly dangle which is a new experience for me. I’ve been using it at the minimum height and it’s perfect for me. Very pleased with the result and has saved a very expensive chair!
