CES 2014: This Smart Mattress Tracks Your Zzzs [Video]

Huzzah! A health monitor with nothing to wear!

The problem with wearables is that you have to always wear them, even to bed. SleepNumber, this year at the Consumer Electronics Show, introduced a way around that. The x12 bed uses pressure sensors underneath its air-based mattress to see how well -- or badly -- you sleep. It's a little out there, we admit, but how could we possibly ignore a smart bed? Check out the video to see how it works.
