Eight Sleep Smart Mattress is a successful Indiegogo crowdfunded project. Eight Sleep is a high-tech mattress with intentions of meeting a wide array of sleeper’s needs, then improving their sleep with their newly developed sleep tracking technology. It is very comfortable. Measures lots of sleep metrics. Warms each side of bed independently. You can manually switch between Day and Night modes in its companion app, which can trigger any combination of functions using IFTTT. Its companion app works on iPhone and Android phones.
Its sleep tracker works with any mattress. The fact that Eight’s sleep tracker is removable means you can enjoy all the smart capabilities without being committed to the company’s mattress.
