1. A mattress comprising:
a stack of four mattress elements comprising:
a first zonal mattress element having a softer upper section, a softer lower section and a firmer midsection that is firmer than said softer upper and softer lower sections, each section being about a third of a length of the first zonal mattress element and occupying the full width of the first zonal mattress element, the three sections configured to provide support to maintain an aligned spine posture for side sleeping by having the softer upper section support a shoulder area, the firmer midsection support a hip area, and the softer lower section support a leg area;
a firm uniform mattress element, said firm uniform mattress element having a first side in direct contact with a side of said first zonal mattress element;
a soft uniform mattress element, said soft uniform mattress element having a firmness softer than the firm uniform mattress element, said soft uniform mattress element having a first side in direct contact with a second side of said firm uniform mattress element;
and a second zonal mattress element identical to the first zonal mattress element, said second zonal mattress element having a side in direct contact with a second side of said soft uniform mattress element
wherein the mattress provides a first zonal variation when the mattress is disposed with the firm uniform mattress element on top of the soft uniform mattress element, and a second zonal variation when the mattress is disposed with the soft uniform mattress element on top of the firm uniform mattress element, and the difference in zonal variation is due to the relative positioning of the firm uniform mattress element and the soft uniform mattress element;
