ABSTRACT:
A mattress is formed with an upper variable firmness section covering a lower section of generally uniform firmness. The upper section is divided along its length into four transversely extending regions, namely, a head, an upper torso, a lower torso and a leg support region. The lengths of the regions approximate the average lengths of a preselected range of corresponding human body parts. Thus, the head support region approximates the length of a head and neck; the upper torso region approximates the length of the torso from the neck to the waist; the lower torso region approximates the length from the waist to the crotch; and the leg support region approximates the length of the legs from the crotch to the feet bottoms. Each region is of a substantially uniform firmness, but the firmness is varied from one region to another. Thus, the upper torso region is the firmest region; the head and lower torso regions are about of the same firmnesses and the leg support region is the least firm. The upper section is formed of a resilient, foam rubber-like material which is indented in patterns to provide numerous closely spaced apart hills surrounded by indented valleys, with the firmnesses of the regions being varied by varying the heights of the hills.
