Keep to a similar--not exact--wood finish match. In this light room with the crazy amazing green and wallpaper at the headboard, the wood is different but dark, helping ground the room and keep a pleasant variety. Though the headboard and frames and lamp are darker than the wall shelf and benches throughout, they all contribute to (rather than compete with) each other.
the bench at the end of the bed is great and I see it in almost all the bedrms in 2009. Also instead of art work above the bed they have gone with what looks like wall paper and again this works for me.
