Abstract: A clamp is provided. The clamp has a first member, a second member, and a biasing element assembly pivotally connecting the first member to the second member. A first end of the first member can be pivoted to a position that is essentially adjacent to a second end of the second member and locked into place. A first slot is formed on a first surface of a first cushion. A second slot is formed on the second surface of a second cushion. A first member of a clamp is inserted into the first slot and a second member of the clamp into the second slot, so that a portion of at least one layer of bed covering materials can be positioned between the clamp first member and the clamp second member when the first member is locked into place.
