The bed frames in the Athletes Village at this year's Olympics will be made of sturdy cardboard. The single bed frames will be recycled into paper products after the games. The mattress components—the mattresses are not made of cardboard—will be recycled into plastic products. The mattress is broken up into three distinct sections, and the firmness of each can be adjusted. The idea was to use materials that could be remade after the Olympics and Paralympics. But the cardboard frames and supports should give the rooms a spartan look.
