There are Aaron’s Furniture Rentals all around Maine and when they held annual conference in Maryland they decided to try and break a world record. They broke it.

It was the Guinness World Record for the longest human mattress domino chain. Aaron’s had 1,200 people holding a mattress behind them and falling backward into each other, one at a time, like dominos.

The previous record was 1,150 but Aaron’s did 1,200 and it took 13 minutes and 38 seconds. The 1,200 mattresses will be donated to a Washington organization that provides shelter to homeless families.
