Knocking over hundreds of human dominoes sounds like a really dangerous game, but when each participant is strapped to a mattress the game is safe enough for the folks at Guinness.
But when you're trying to set a world record for largest human mattress dominoes the tricky part isn't safety- it's getting 1,200 people lined up properly then making sure they all fall down in turn.
Twelve hundred Aaron's Inc. employees clung to mattresses set up over 70,000 square feet of space in two exhibit halls, then they all fell down to take the Guinness World Record away from German furniture company Höffner, who set the record in 2012.
