Empty Site #9: Bed

Similiar to the chair as an empty site, a bed's 'emptiness' comes from our assignment of the word 'empty' to describe an unnocupied bed. Is a bed still 'empty' if it has an object in the same negative space as a person would occupy?

Also, the size of a bed does not affect how much of an object (or how many people) must be in the bed for it to be considered 'not-empty' (rather than full), i.e one person on a huge bed is just as 'not-empty' as one person on a tiny bed.
