Ford has invented a prototype bed that automatically rolls selfish sleepers back to their side of the mattress whenever they stray onto the other half.
The car maker has adapted the lane-centring assist technology used to ensure drivers remain in the middle of their lane into a concept dubbed the Lane-Keeping Bed, in a bid to help sleep-deprived partners pushed to the edge of the bed at night.
Pressure sensors detect when a person moves from one side of the bed to the other, and gently rolls them back to their side with the help of an integrated conveyor belt.
