Sleep monitoring specialist Beddit today announced the availability of its best-selling wireless sleep tracking device nationwide. Beddit Sleep Monitor is available now in Bed Bath & Beyond stores, in time for the holiday season.

Beddit Sleep Monitor is an ultra-thin film sensor, placed under the bed sheet, which measures the user’s vital signs and sleep activity—without wires or devices touching the body. Beddit sends the sleep data over Bluetooth to a companion app on a smartphone where the data is analyzed using sophisticated algorithms based on ballistocardiography (BCG). Each morning Beddit’s mobile app presents a sleep analysis and coaching tips on how to improve sleep.

“There is a lot of excitement around wearables and tracking sensors,” says Lasse Leppakorpi, CEO of Beddit, in a release. “But while other devices are still in the speculative stages, we’re already manufacturing and retailing our devices around the world. What sets us apart from others in this category is freedom, you do not have to wear anything on you while you sleep. The sensor attaches to the bed, not you.”

To support the launch, Beddit will embark on a US Tour with world-renowned sleep research scientist, Markku Partinen MD, who will be in-store to give customers hands-on coaching advice on how to improve their sleep. The tour will visit five Bed Bath & Beyond stores in New York, Chicago, Los Angeles, and San Francisco between November 10 and 15.
