If you’re the kind of person who moves around a lot when you sleep, then you know that keeping your blankets off of the floor is a near impossibility. This means that they get dirty faster, which increases you laundry load faster. Blanket Blocker is designed to keep your covers from slipping off of your bed while you are asleep at night so that they don’t become a tripping hazard. It also apparently has a certain amount of entertainment value for kids, based on the video. For $25, backers get a set (two) of them, but an expected delivery isn’t noted.
