Abstract
A method of making a mattress component includes providing a first layer of a first material. Mating patterns are shaped in a surface of the first layer in areas corresponding to a position where hips and shoulders of the user will rest on a mattress. The mating patterns in the surface of the first layer result in a greater effective thickness of the first layer in areas corresponding to the position where the hips and the shoulders will rest, and a lesser effective thickness of the first layer in other areas. A second layer has a second material with different properties than the first material. Mating patterns are shaped in a surface of the second layer in areas corresponding to the mating patterns of the first layer and shaped to substantially match with the mating patterns of the first layer.
