Irish gymnast Rhys McClenaghan has debunked the idea that the cardboard-framed beds for athletes in the Tokyo Olympic Village were not strong enough to withstand vigorous activity and were therefore “anti-sex” by recording himself jumping up and down on the one in his room.

Organisers said athletes competing in the Games would sleep on bed frames made from recyclable cardboard and mattresses made of polyethylene materials that would be reused to make plastic products after the Games.

Manufacturer Airweave said the beds could support around 200 kilograms but some media reports claimed they were made out of cardboard to collapse under the weight of more than one person .

American distance runner Paul Chelimo wrote on Twitter that the decision to have cardboard beds was “aimed at avoiding intimacy among athletes.”

McClenaghan took to Twitter to debunk the idea. “The beds are meant to be ‘anti-sex’ ... They’re made out of cardboard, yes, and apparently they’re meant to break at any sudden movements... It’s fake! Fake news,” he said while jumping on his bed in a video clip.

The official Olympics Twitter account thanked McClenaghan in a tweet on Monday for clearing up the matter and added: “The sustainable cardboard beds are sturdy.”
