Comfort meets technology in the Eight Smart Mattress. The Eight Smart Mattress provides the perfect comfort and support for any sleeper, in particular couples. Through its app, it tells you how you are sleeping, keeps you warm at night, and wakes you up at the right time. It’s just the perfect mattress, but smart. Eight has two sets of controls—one for you, and one for a partner if you’d like. Both of you can access all of Eight’s features, receive individual sleep data, and warm each side of the bed at different temperatures.
