This specific usage of the verb "to make" is rather dialectal and should not be deemed stadard English. True, in some parts of the U.K., you will actually hear a speaker say that "the bed is done", but it sounds rather incorrect.
I would go more for the verb "to lay out".
--> I laid out the bed finally. Now everything is in (its) place.
Also you could use "to finish", albeit it has a more general meaning.
--> I finished the bed (= the bed was arranged)
In addition if you want to sound a bit more regional, i.e. British, you could definitely avail of "to fettle" meaning "to arrange" to set up in order or "to settle".
"To make", on the other hand, conveys the idea of creating or constructing. So to me a sentence like "the bed mas made" sounds like " the bed was finally ready to be used (= in the sense the it has gone through the process of being prepared/built for other people to use it)
Hope that hepls,
All the best.
