Re: Roc n soc nitro or tama 1st chair round top?
Hydo shouldn't loosen, but the cylinder may die after a while. mine doesn't lean, I use an old pearl screw type and its still solid (1985). Its not that the hydro is a bad design, I just wonder about transport, what if the lever is hit and the height changes? the screw type stays where it is. I don't know? Aslo, my office chair right now is hydro and when I sit, it drops a few inches, do the drum thrones do that too? that would bug me if it did.
