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

Build quality and performance are excellent. Right price also.

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.

Nice product

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
