If you take sleep seriously, you can’t do much better than this smart mattress. Using thin water channels, it dynamically regulates its temperature throughout the night based on your presets and biometric feedback, which its inventors say can help you consistently sleep better. An array of sensors track sleep phases, heart rate, respiratory rate and more for up to two people, delivering a “sleep fitness score” via a companion app. “There’s a bunch of trackers that can tell you how bad you slept last night,” says CEO and co-founder Matteo Franceschetti. Pod, he says, takes that data and uses it to actually improve your sleep. Even at $2,135 for a queen, the Pod sold out in just 15 days when it launched in February. —Alejandro de la Garza
