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.

An elongate zipper extending between a first end and a second end, comprising:
- a first side of the zipper extending between the first end and a second and having a multiplicity of discrete first elements;
- a second side of the zipper extending between the first end and the second end and having a multiplicity of discrete second elements interlockable with the first elements of the first side to removably attach the first side of the zipper to the second side of the zipper;
- a stop included in the first side of the zipper at the second end of the zipper;
- a starting lug included in the second side of the zipper at each of the first end and the second end of the zipper;
- and
- wherein the second side is attached by an edge without elements to a closure edge of a reversible material and the first side is attached by an edge without elements to a closure edge of other materials, whereby the reversible material is adapted to be reversed with respect to the other materials such that the second end of the second side is in engaging relationship with the first end of the first side.
