yo i dont know bout them seats like the roc-n-soc an those other ones with tha handle that lets you up or down cause at a concert i was playing on one, and it kept going down, i couldnt stay at the same height throught the concert, it got on my nerves! so i prefer the original ones, like the gibralter morticycle throne, with the handle that you turn that lets you move, but thats just me....
