ABSTRACT:
A mattress assembly includes a mattress base and a mattress top having first and second major surfaces extending to a peripheral edge. Slidable fastener means disposed between the mattress top and the mattress base removably and rotatably attaches the mattress top to the mattress base. In an associated method for moving a body depression in a mattress, the mattress top is attached to the base with at least one zipper having a first side and a second side. Opening the zipper permits removal and rotation of the mattress top relative to the mattress base to move the body depression to a different position. Closing the zipper reattaches the mattress top to the mattress base.
