Beware!!   Some retailers use a tag which says by the makers of Beautyrest. These are not as good a mattress. In addition some of the larger retailers get Simmons to morf the levels making a bed that sounds like the next level but without all of the advantages. This is done so that when you go to a store that is not doing this you think you are comparing equals your not.
