A mattress component includes first and second layers to be assembled in a mattress over which a user will lie. The first layer of a first material has different properties than the second layer of a second material. The second layer has a surface underlying the surface of the first layer. Mating patterns are formed in the surfaces of the first and second layers. The mating patterns in the first and second layers are designed to substantially match the surfaces of the first and second layers with each other. The mating patterns in the first and second layers result in a greater effective thickness in one of the layers in areas corresponding to a position where hips and shoulders of the user will rest on the mattress, and a lesser effective thickness in other areas.
