#212: “The ancient Greeks were the first to use bed springs. They fashioned them out of braided leather thongs and hung them between opposite sides of the bed.”

True.

The wording is a little off here, so I’ll try to clarify. The Greek bed frame was made of wood, then strips of hide were woven across and down the bottom part of the frame, being stretched between parallel sides of the frame. Then animal skins were piled onto the woven strips for the actual bed. So they were bed springs, in the sense that they supported the sleeping surface.
