Claims12
A pressure relief support system for a mattress comprising:
- a plurality of elongate air cylinders arranged in a parallel relationship to form the innards of a mattress;
- a plurality of slats forming a row of slats extending across the length of the air cylinders, each salt extending substantially perpendicular across the plurality of air cylinders and being substantially parallel to, and in juxtaposition with, an adjacent slat;
- a plurality of individual foam strips, each foam strip supported by the topside of one of said slats, said foam strips extending substantially the length of the slat;
- and
- means for securing each of the slats over the air cylinders wherein any of the air cylinders can be removed without disturbing the slats or remaining cylinders.

A pressure relief support system for a mattress comprising:
- a plurality of elongate air cylinders arranged in parallel relationship;
- a casing surrounding the air cylinders having a plurality of sleeves therein each sleeve extending perpendicularly across the cylinders within the casing and being substantially parallel to, and in juxtaposition with, and adjacent sleeve;
- a plurality of slats having an arcuate cross section, said slats insertable within the sleeves thereby being arranged in a substantially parallel relationship with each other and extending substantially perpendicular across the top of the air cylinders thereby forming a row of slats extending across the length of the air cylinders;
