Waking up in the middle of the night drenched in sweat or freezing cold puts a huge damper on your quality of sleep. If you've tried all the cooling and heating mattresses and pads and still aren't getting a good night's rest, it might be time to bring some smart technology to the table.

Eight Sleep specializes in smart mattresses with thermoregulation. And it's not just the so-called cooling foam you'll see advertised by other mattress brands. Eight Sleep's mattresses and mattress covers use water-driven cooling technology, powered by a smart hub that sits at the side of the bed. You can use an integrated app to set your ideal sleeping climate, and the mattress or cover will work silently all night long to help you stay at that temperature. There are also tons of other smart features like sleep tracking, heart rate tracking, and even gentle alarms — all from your mattress.  Read more...
