Eight Sleep Pod 6 adds 18 sensors for no-wearable sleep tracking

Eight Sleep announced the Pod 6, jumping from two biometric sensors in the Pod 5 to 18. The array sits under the bed cover and tracks heart rate, breathing rate, heart rate variability — beat-to-beat variation — snoring and sleep stages without a wearable. It can separate two close sleepers and filter out pets, with data viewable in its app.
