Component with multiple layers

A mattress, comprising:

• a bilayer foam topper, which includes a top layer having a high thermal conductivity foam and a bottom layer with foam;
• a high thermal conductivity dual gel foam layer disposed below the bilayer foam topper, wherein the dual gel foam layer comprises a gelatinous matrix that exhibits substantially no flow when at a steady-state and a thermally conductive material selected from the group consisting of carbon black, graphite, carbon nanotubes, calcium carbonate, metallic flakes, and graphene;
• a foam layer disposed beneath the high thermal conductivity dual gel foam layer and having a top surface comprising a continuous foam matrix and discrete depressions interspersed throughout the foam matrix, each depression having a diameter of about 2 inches, wherein the depressions are spaced about 5 inches apart from one another when measured in a direction parallel or perpendicular with a side of the foam layer, and wherein fewer than all of the depressions are filled with gel discs having a thickness of about 0.25 inches;
• and
• a core layer disposed beneath the foam layer that includes at least one of a foam core, a gel foam core, a latex core, an inner spring layer, a layer of individually wrapped coils, an air inflated system, and a liquid system,
• wherein the foam layer disposed beneath the high thermal conductivity dual gel foam layer maintains a depth of compression in a standard force compression test with a 13.5 inch platen less than that of an identical layer without the depressions and plurality of gel discs from about 60 to at least about 250 lbs of load.
