A simple new accessory can bring an end to the nightly struggle over the bed covers, by securing them to your side of the bed.

The Cover Clamp is designed to lock the edge of the duvet to your side of the bed, preventing your partner unwittingly stealing it during the night.

Combining the clamp with the grip pad that is placed under that mattress creates a hold that can withstand even the most forceful of tugs, the creators say.

It can also be attached to the bed frame using a strap. There’s also a special buckle which can be used to loosen the grip so you can get out of bed at night if you need to.
