A mattress supporting a reclining body with low body pressure and in alignment.
The mattress extends in a lateral direction from side to side and extends in a
longitudinal direction from a mattress head to a mattress foot where the mattress
includes a head part, a shoulder part, a waist part, a hip part and a leg part.
The reclining body has a displacement profile that causes the mattress to undergo
differing vertical displacements when supporting the reclining body. The mattress
core has displacement parameters varying to match the displacement profile of the
reclining body while supporting the reclining body with low body pressure. The
core has 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.
