The Purple Mattress is famous for the hilarious commercial featuring what's known as the “human egg drop” test, a stunt designed to show the mattress is so supportive and comfortable that eggs won't break when a body falls on top of them. Inside Edition’s Chief Investigative Correspondent Lisa Guerrero wanted to see if the human egg drop test really worked, so she tried it out herself. Supervising the test was Professor Ali Sadegh of New York's Grove School of Engineering, as well as stuntman Bob Cotter. Right away, Cotter realized there was an issue. #InsideEdition
