VARYING FIRMNESS MATTRESS ABSTRACT OF DISCLOSURE A standard size mattress is formed with four longitudinally arranged regions, i.e., a head, an upper torso, a lower torso and a leg support region, for supporting a person comfortably and substantially level. The length of the head support region is equal to the approximate height of a person's head and neck. The length of the combined torso support regions is equal to the approximate height of a person's torso from the crotch to the juncture with the neck, with the upper torso region being roughly two-thirds and the lower torso region being roughly one-third of the length of the combined torso support regions. The length of the leg portion is equal to approximately the height of the legs from the crotch to the bottom of the feet. Thus, the lengths of the four regions are roughly in the ranges of 18%, 23%, 14% and 45%, respectively, of the length of a typical standard mattress. Each of the head, leg support and the two torso regions are of a single, constant support firmness, which differ from their adjacent regions. The upper torso region is the most firm, the head and lower torso regions are of about the the mid-firmness, and the leg support region is least film The lengths of the torso and leg regions vary for different length standard mattresses while the head region remains approixmately the same length for different length mattresses.
