Possibly the best place I have found to test out seats was the waiting room in the service department at the Petro in Bordentown, NJ, they have a bunch in there to try out. I would definitely test out a model of seat before buying new, as some of the high end leather seats are upwards of $800 each with Petro prices, just find what you like and get better deal on internet or ?. National is a pretty good OEM seat, but ##### some of those expensive leather jobs make even them feel like park benches!! I've always lived with what was in the truck, but if I started all over I would get one really good drivers seat, and keep and swap the stock one back in when I sold the truck, I imagine a good leather upholstered seat could live through a couple of trucks the comfort making it worth the cost.
