Patent ID: 7036172

Claim:
A mattress, extending in a lateral direction from side to side and extending in a longitudinal direction from a mattress head to a mattress foot, for supporting a reclining body, said mattress including a head part, a shoulder part, a waist part, a hip part and a leg part, said reclining body having a displacement profile, said mattress comprising, a core extending in said longitudinal direction and in said lateral direction, said core for undergoing differing vertical displacements when supporting the reclining body, said core having displacement parameters varying to match the displacement profile of the reclining body whereby the reclining body is supported by low body pressure, said core having a plurality of regions where the vertical displacement in one or more of the regions varies to match the displacement profile of the reclining body to maintain the reclining body in alignment, said core including one or more foam members having structural modification where the one or more foam members at different longitudinal positions exhibit different displacement parameters including different ILDs to support the reclining body with low body pressure and exhibits different vertical displacements to maintain the reclining body in alignment.
