Today I get into a product I felt I needed, to track my sleep habits as well as incorporate comfort and warmth when I sleep. The Eight Sleep tracker is a mattress cover that tracks the whole bad (two sides to accommodate two people) sleep patterns (awake, lite sleep, deep sleep Rem sleep) into an app that has great summaries and detail to improve your sleep. It also is a comfortable mattress pad with a heater incorporated. Here's my review because I had to order a new one.

A sensor layer that fits over any mattress and instantly turns your bed into a smart bed. Review your sleep data, use the dual zone warming feature for an extra cozy bed, connect to almost any wifi-enabled device in your house
