The most epic pillow-related event of the 2016 calendar! If you fancy beating the sense out of your friends and strangers too, but with no harm done, then this collective pillow fight in central London is for you. All in the name of International Pillow Fight Day, the mayhem of fluffy fighting starts in Trafalgar Square and lasts until your arms can take no more! At this point, most people take their pillows to St James's Park to relax in the sunshine, perhaps with a nice cold beer too... Enjoy the cold side of the pillow differently in this celebration of International Pillow Fight Day!
