Strong wind blows dozens of air mattresses through Denver park

Dozens of air mattresses cartwheeled their way across a park in the US city of Denver on Saturday after strong winds whipped through the neighbourhood. Eyewitness Robb Manes, who filmed the bizarre spectacle, described the incident as the ‘great mattress migration of 2019’.  According to local reports, the mattresses had been set out for an event called ‘The Bed Cinema’ later that day, where cinemagoers could reserve an air mattress to watch the film in the open air.
