Largest human mattress domino

The largest human mattress domino consisted of 2,016 participants and was achieved by Rotary International District 1120 (UK) in partnership with The World Record Attempt, at the ExCel London exhibition centre, UK, on 22 March 2019. The event was organized to raise funds for the End Polio Now campaign, which aims to eradicate polio worldwide. The participants were arranged in a series of rows, each lying on a mattress, which was then pushed over to create a domino effect. The attempt was successful, with all 2,016 participants falling in succession, setting the new world record for the largest human mattress domino.
