So I've seen a lot of post about these Clazzio seat covers but I can't seem to find an answer to a question that I have about them... I, along with many other people, find the seats in the Prius to be very uncomfortable and they hurt my neck and back. Do the Clazzio seat covers add a good amount of comfort to the seats? I know they are meant to have 15mm of memory foam in them, and I was wondering how much of a difference that they actually make before I dish out the $450. Any advice would be greatly appreciated. Thanks!!! Jon
