The Dreampad uses transducer technology to play music through vibration, which travels through the pillow to the listener’s inner ear. In the process, it triggers the body’s relaxation response in the parasympathetic nervous system (PNS), according to manufacturer Integrated Listening Systems.

On Sunday, Nov 5, the sound therapy for sleep device appeared on ABC’s entrepreneur reality show Shark Tank.

While it was originally developed as a therapy tool for children on the autism spectrum, Dreampad CEO Randall Redfield says he recognized its potential for helping people of all ages fall asleep faster. “Being on Shark Tank was an experience of a lifetime,” he says. “It is a long way from the therapy origins of the Dreampad and it’s fun to see how the consumer world is reacting to the product. The sharks are tough investors but they’re also savvy consumers, and it was gratifying to see how much they liked it.”

The Dreampad is available in a variety of sizes, including Memory Support, Firm Support, Medium Support, and Slim Support.
