The trick with a double bed is to simplify the entire look of the room (no clutter) and go with a more "reserved" look for the room. Keep the room as clean as possible; otherwise it may look as if the bed is lost at sea with your belongings!

Those days they were known to be made of wood. The popular practice during this period was to place them in the centre of their rooms. The objective behind this was to highlight it as one of the primary pieces of furniture of that particular room. Generally, people took immense pride in showing their prized possession.
