As Pappagray said, it's about the installer. The good ones will steam the seat cover after they put it on. It's like hydrating the leather and the steam takes the wrinkles out.
You should download the color chart and check it out and find the color that makes you Happy. They can do the perforated seat covers too. I thought that it was kind of fun in the design your own seat section. You can get as crazy as you want there. Pretty Neat stuff!
