Airweave, a Japanese bed company, is making 26,000 beds (18,000 for the Games and 8,000 for the Paralympic Games) out of what the company is calling "high resistance lightweight cardboard." Mattresses will be polyethylene. The use of cardboard is in keeping with the Games' theme of sustainability, organizers said. Completing the cycle, organizers will convert the cardboard bed frames into paper products and the mattress parts into plastic for other items.

Other ways that the Tokyo Games will emphasize the Olympic commitment to sustainability:

• The medals handed out to the top three finishers in each event will be made of metals collected from mobile phones and other electronic devices. Olympic officials conducted a large public donation campaign.
• Also made from public donations will be the podiums used in the medal ceremonies; shampoo bottles and other plastic items will be the basis for the materials out of which the podiums will be crafted.
• The Olympic Village plaza will be made out of sustainably sourced timber, which, after the Games, will be converted to other public use, such as in buildings or as park benches.
• Electricity needed to run the games will come from renewable sources.

The Games run July 24–August 9.
