If you are looking for seats that are not vinyl so that your butt won't melt, why not just get some seat covers?
You do not have vinyl seats I take it, haha. They are SO vinyl, that even covers wont help unless they are the thick ones...which then bunch up and look like a clam.
I have looked into them but havent found a good one yet. Maybe i'll venture to wally world and just keep the receipt if they dont do the trick. But in my experience with 2 types of covers, the vinyl still wont let your butt breath and sweat just explodes out.
