This could end many an argument!

A new smart bed could be the saving grace of your relationship.

Car maker Ford has invented a prototype bed that automatically rolls sleepers back to their side of the mattress when they stray onto the other half.

They’ve adapted their lane-centring technology to make the Lane-Keeping Bed, which they say will help partners who’re pushed to the edge of the bed at night.

Pressure sensors on the bed detect when a person moves from one side to the other. It then gently rolls them back to their side with the help of an integrated conveyor belt.

“When sleeping together, many couples each have less space than a small child has in a single bed,” sleep expert Dr Neil Stanley told BreakingNews.

“Humans are most vulnerable when sleeping, so we’re programmed to wake when something or someone touches us unexpectedly.

“If someone moves onto your side of the bed this defence mechanism will kick in and you’ll have a broken night, often while they continue to sleep soundly. I’ve seen it ruin relationships.”

The Lane-Keeping Bed is just a prototype and there are no current plans to put it to market.
