I wonder why they don't have a single sized one. Because where cuddling is optional on a double bed, it pretty much is the only way to share a single bed.

Also interesting to consider is that it won't fit all types of beds. As with a lattice bottom bed, slices could fall through, and with a box-spring bed the slices at the top and bottom of the mattress could simply slip over the edge.

It looks like they run a pair of fasteners through the whole stack of slices, to prevent them from separating too much.

That will definitely prevent the ends from falling off. Not sure how effective it will be on a slat base.
