Ford invents 'smart bed' that rolls selfish sleepers back to their own side

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-centering 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, the Daily Mail reports.

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.

The Lane-Keeping Bed was created as part of an exploratory project of the company's technology aimed at tackling everyday problems and remains a prototype, meaning there are not any current plans to put it to market.
