Yes You must lay on top off it, but it goes under your mattress It’s easy enough to maneuver to the center of your bed, but it will pick up another sleeper as it doesn’t just identify you It will not do two reading at once -so as long as you are on it, you’ll be fine
Sorry, there was a problem. Please try again later.company website says to position it under the mattress, near chest height. For 2 people they recommend one on each side of the bed. It plugs into usb or wall outlet. We use it in a twin bed, so I can't address proximity required for accurate readings.
