Smart devices are on the rise nowadays so it´s no surprise they’ve now reached the item you spend more time on: your bed. The Eight Sleep Tracker is a sensored mattress cover that has some special features built in to it, such as: a group of motion sensors that gather data when you’re sleeping enabling the app that comes with it to track and assess your sleep quality during the night. It also comes with a heating option, different for each side of the bed so when you climb on it it’ll be warm and cozy, again just use the app and set how warm you want it to be. Plus you also get a smart alarm that wakes you up lightly and feeling refreshed during your lightest sleep stage. Tracks sleep for one or two people.
