1. A pressure relief support system for a mattress, comprising:

  • a substantially rectangular casing, said casing including an inner area removably supporting a plurality of respective sealable fluid filled elongate cylinders therein in a predetermined substantially parallel arrangement along the length of a longitudinal first direction of said casing so as to substantially define the shape and size of said mattress;

    a plurality of substantially mutually parallel sleeves formed on a selected first side of said casing, said sleeves being situated over the length of said elongate cylinders and extending in a lateral direction substantially perpendicular to said first direction of said casing, and said sleeves being formed for removably receiving respective independent slats therein for providing independent lateral slat user support for reducing longitudinal shear forces on such user;

    a plurality of individual relatively firm slats respectively and removably received in said plurality of sleeves such that selected of said slats may be easily alternately inserted into and removed from respective of said sleeves without disturbing the remainder of said slats and without disturbing said predetermined arrangement of said cylinders;

    selective closure means for selectively exposing said casing inner area such that selected of said elongated cylinders with selected amounts of fluid therein may be easily alternately inserted into and removed from said casing inner area without disturbing said arrangement of the remainder of said cylinders in relation to said casing and without disturbing said slats received in their respective sleeves; and

    support means within said casing inner area for forming predetermined compartments for the insertion of at least selected of said elongate cylinders therein so as to form said predetermined arrangement thereof.
