Cute! Dunnage is not, strictly speaking, exclusively the name or term for the bracing used in ship's holds for securing cargo. The term gets used in the transportation industry to describe any type of materials, wooden timbers or studs, heavy plywood, welded braces or spars, or even surplus skids that get used to brace and secure shipments from moving or tipping over, or collapsing. Got to deal with the stuff a lot when working with sea cans of various lengths. For some reason old mattresses were a favorite stuffing material for some shippers.
