The Zeo Personal Sleep Coach ($400) consists of a headband with a SoftWave sensor to accurately track your unique sleep patterns, and a bedside display that shows the time, a graph showing your pattern of sleep phases from the night before, a "ZQ" single-digit representation of the quantity, quality, and depth of your sleep, a count of how long you actually slept and how long it took you to fall asleep, and more. For even more information, pop the SD card out of the display and into your computer to upload your data to Zeo's website, where you can get an even more detailed look at your sleeping patterns, and see personalized tips for getting your best night's rest.
