Abstract
A single layer mattress cushion formed of a common material throughout and having three distinct convoluted zones arranged along its length. The first zone is specifically configured for supporting the shoulder and head area of a person while the middle zone is specifically formed for supporting the torso area of a person and the third zone is specifically formed for supporting the feet and lower leg portion of a person. Each of the cushion's three separate sleep areas has a different compression modulus such that the middle zone provides a maximum dual level peak support for the torso area while the first zone section provides a mid-range support function to the head and shoulders of the person and the third zone section provides light and well ventilated support for the legs and feet of the user. The maximum support zone for the torso is provided with two different sets of peaks with one set having a higher height than the other set so that the initial contact which is made between the person and the higher level peaks is soft and gentle and, as the person further presses down upon the middle zone, the lower peaks come into action to achieve proportional support in the heavier area of the person's torso.
