Abstract
An endoskeleton elastomer that variably impacts the mattress firmness head-to-toe is described. The elastomer fills voids cut into the foam using contour cutting or spherical cap-shaped cutouts. The elastomer is poured as a hot liquid into the voids, and cools to a solid elastomer. The specific incarnation involves the creation of a set of parallel inclusions at the center of the mattress or a set of spherical cap-shaped cutouts that help prop up the hip area to maintain proper spinal alignment by firming the center of the mattress. The depth, width, shape, spacing, elastomer durometer, and location (both head-to-toe and depth in the mattress) may be varied to impact firmness in any desired manner. The mattress may also include a series of horizontal-oriented cutouts that are cut into various portions of the mattress layers. These cutouts may extend along the width of the mattress and may be placed at portions of the top and portions of the bottom of the mattress.
