Abstract
Mattress assemblies including a foam layer comprising at least one porous surface, the at least one porous surface comprising targeted portions thereof including a cured polymer impregnated into pores of the at least one porous surface, wherein the cured polymer alters a firmness dimension of the foam layer relative to non-target portions without the cured polymer.
Claims10
A method of forming a mattress assembly having zoned firmness, the method comprising:
- preparing an untreated foam layer comprising a porous surface;
- applying a liquid monomer and/or polymer to selected target areas of the porous surface;
- infiltrating the liquid monomer and/or polymer into the untreated foam layer in the selected target areas, thereby forming localized regions of impregnated foam;
- and
- curing the liquid monomer and/or polymer in the localized regions of impregnated foam, thereby altering a firmness of the mattress assembly in the selected target areas relative to non-target areas of the untreated foam layer.
