I find it humorous that some maker has developed a gimmick machine to tell you what bed you need. That's hilarious. Ever wonder what ever happened to those snake oil salesmen from the 1800's and 1900's? They went into the bedding business. There are more false claims and smoke / mirrors in the bedding business than any other aspect of the home furnishings industry. My thoughts on bedding are well documented here, read back into the forum if you like and you will find them.
