Guesthouses have a problem with flexibility. Often they can’t supply separate beds for people who need them.
Today’s invention is a divider that bolts to a double bed to allow two unrelated people to share it…but without ever coming in contact with each other.
This could be made to any height and constructed of soundproof material.
The lower edge is bowed downwards to press down into the mattress so that no gap appears underneath, even if your bedfellow is heavy.
