Sleep tracking has been around for a while, but the company Durmet has its own Smarttress mattress, which will let you see when your bed is being used even when you are not home. Crazy right? They created an app called Smarttress, which they call a lover detection system, that will send notifications to your phone if a partner may be cheating.
This bed is not cheap. It cost around $1,750 and is filled with sensors in the springs that vibrate when the bed is in use. Not only does it detect the bed vibration, but it also detects speed, duration, impact and intensity!
