i have a stanley-bostitch finish nailer that is awesome, however it is not a stapler. bostitch tools perform great. i'm not sure if they make an air stapler that will accept 1/4" staples. i'm sure you already know that 1/4" is the max length you want to use on a seat cover. i have a stanley electric staple gun and it won't even shoot 3/8" staples deep enough into a 2x4 at max setting. hope this helps you cam.
