The Electro-Magnetic Alarm Bed, invented by John Crane in London in 1856, was a novel device intended to help heavy sleepers awaken more effectively. This contraption integrated with an alarm clock utilized an electromagnet to tip the sleeper onto the floor when the alarm sounded. Although it amused the public and was featured in exhibitions, it was never widely adopted. The invention is a testament to the 19th-century spirit of integrating technology with daily living.
