Mattress ratings are not easy to find. While you can easily access a variety of consumer mattress reviews, getting objective ratings in a systematic way is much more difficult. There are several reasons for this.
One reason is that mattress manufacturers seem determined to avoid any objective rating system for their mattresses. They do this by making it very difficult to find the same mattress model in more than one outlet.
As the Consumer Reports mattress guide points out, if you shop for one model, say the Sealy Blankety-Blank, at a mattress sale at high-end department store, and then head over to your mattress discounters to see if you can get a better price — you will not find that same mattress there.
