Face it: You need more sleep. Casper, which has gone from podcast-sponsoring, mattress-in-a-box-shipping, memory-foam-evangelizing startup to high-priced bedding and furniture company, also thinks you need more sleep -- or at least a better way to fall asleep. That explains why it's released the Glow, a smart light built to lull you to sleep, help you get out of bed, and keep you safe from self-inflicted foot injuries in the middle of the night. It sounds like a good idea, but do you really need a fancy nightlight to catch some zzz's? The Casper Glow is a wireless, gesture-controlled LED lantern that dims or illuminates over the course of 45 minutes to ease you into a deeper sleep, or gently rouse you from said sleep in the morning.
