How do you get the chair hydrolics to hold my wieght. I'm not fat either.
if it will not hold your weight that means that the cylinder is bad.
Replacing the cylinder is usually not an option however you could set the height, then drill through the shaft and put a bolt in it to hold it to that height. Another way is to take the cylinder apart and put a collar in there, a piece of pipe of the correct height to hold the chair where you want it.
