toss it in the dryer for about 25 min, square the front, put in a few staples, square the back, a few staples, stretch the middle where the seat transitions from the front to back where the curve of the pan is, staple, and then work the rest. Done a bunch this way, Guts will install a seat cover for free if you buy a cover and send them your seat. Sometimes it is nicer to have someone do it that does it everyday.
