an internal support wall attached to the interior surface of the top panel and the interior surface of the bottom panel, the internal support wall being air-permeable and forming a central chamber within the airtight chamber that has a shape generally equivalent to the mattress shape;
a plurality of air-permeable corner support walls, each air-permeable corner support wall extending from the interior surface of a corner formed by adjacent side panels to a respective corner of the internal support wall;
a first lateral support beam attached to a first side of the internal support wall at a first connection point and to the interior surface of a first side panel of the plurality of outermost side panels at a corresponding first connection point; and
a second lateral support beam attached to the first side of the internal support wall at a second connection point and to the interior surface of the first side panel of the plurality of outermost side panels at a corresponding second connection point,
