I can't speak to the mattresses, but I can speak to pillows. I've bought myself a variety of weird pillows, in the the search for that magic something or other. I bought an all-latex pillow, and not only didn't like the feel of it, but the smell never really went away. I later bought a pricey Tempurpedic memory foam pillow and it's what I'm still using.

As they say, you mileage may vary.
