1. A gelatinous composite article in a mattress unit comprising:

  • a foam crib in the mattress unit divided into an upper crib and a lower crib;

    a sealant layer that melts within a first temperature range;

    a first permeable layer over the sealant layer that attaches to the underside of the upper foam crib and melts at a second temperature greater than the first temperature range;

    a first heat formable and heat reversible gelatinous elastomer material over the first permeable layer that fuses to the sealant layer within the first temperature range thereby securing the permeable layer to the gelatinous layer and the first material to the upper crib;

    a second heat formable and heat reversible gelatinous elastomer material having a set of apertures within the lower crib; and

    a second permeable layer having a palm-base attached to the underside of the lower crib, and a set of finger-like structures wherein each finger-like structure secures the second material to the lower crib by having each finger inserted into a corresponding aperture to the top side of the lower crib wherein the distal part of the finger-like structure fuses between the top side of the lower crib and the sealant layer to secure the second material to the mattress unit.
