Abstract: A method of assembling a bedding system includes: operatively connecting a first external surface to a second external surface, each surface having a different material construction, the first and second external surfaces being oriented substantially opposite such that they face away from each other; and arranging the external surfaces on a mattress, wherein either external surface faces the mattress so that the opposite external surface faces away from the mattress. The material construction of the first external surface may have a greater thermal conductivity than the material construction of the second external surface. A trim portion may be positioned in plane and facing the same direction as the first external surface, the trim portion having the second material construction and being continuous with the second external surface. When the trim portion and first external surface are arranged facing away from the mattress, an appearance resembling a made bed is provided.
