Keeps a shaded from the sun, warm to sit on in the winter, and natural, so causes less sweating than vinyl. I got it from ebay, New Zealand Sheep, I think it advertised as a doggy bed. Plus, the original seat is like siting on a 2X4". I removed the seat, layer of sheep, foam, and a Walmart seat cover. Now I shaved off a couple inches of height, and gained some insulating factors. Not for the fashionistas, not worried about what the other 99.9% think of my style. More worried about personal comfort.
