I have noticed a few comments about the Prius seats being uncomfortable. My solution is to use a memory foam pillow. I have found the memory foam molds to your body much better than a regular pillow and I never have to readjust the pillow. It may not satisfy some 64 way power seat addicts but I am very happy with my set up.
Thanks for the posting. Honestly, I was just wondering about that exact solution today! Now I'm going to go out and buy a memory foam pillow!
