Abstract: A reversible mattress includes a first outer region and a core region placed beneath the first outer region. The core region includes at least one core portion. The reversible mattress further includes a second outer region placed beneath the core region. The first outer region, the core region, and the second outer region are each made of latex foam and form the reversible mattress. The first outer region has a first outer ILD (ILDT1) and the second outer region has a second outer ILD (ILDT2) such that the first outer ILD (ILDT1) is lower than the second outer ILD (ILDT2).

Abstract: Embodiments of mattress systems comprise a mattress base, a multifunctional foam layer having a substantially planar top side and a non-planar bottom side contacting a top side of the mattress base, and wherein at least one air passage is present in spacing formed between the top side of the mattress base and the non-planar bottom side of the multifunctional foam layer, and a thermo-regulating gel layer affixed to at least a portion of the top side of the multifunctional foam layer.
