Inventors in Spain have created the Smarttress – a bed that on the outside looks like a normal, comfy mattress but has undetectable ultrasonic sensors hidden inside.
If movement is detected thanks to the 'Lover Detection System', the bed generates a 3D map and alerts you via an app on your phone – it even tells you how many people are in it.
The mattress was designed by Durmet after research revealed that Madrid has the highest number of unfaithful partners in Europe.
At £1,200 it's certainly not cheap, but could this mattress soon be flying off the shelves?
