AnonymousIs my parsing correct?

Yes.

AnonymousNext to the bed - an adverbial.

An adverbial is a modifier of a verb or a supplement attached to a clause, and is always optional. This PP is an obligatory (locative) complement of be.

But who said Anon was studying for an exam in the first place, or even had a teacher? They could just interested in grammar analysis, and if that’s the case, then they should know that ‘adverbial’ is inappropriate for describing the function of the phrase in question.

And what do you think the chances are of an answer like mine causing a student to fail a test?
