While there are also really beautiful metal headboards that you can get, the major disadvantage of buying a metal headboard is that you’re often compromising comfort and style, because they are too uncomfortable to lay against. With wood headboards, however, you can watch TV, read a book or other things you need to be lying up in bed a lot at ease.
Also be sure to measure the bed frame, if you already have one. This will also need to fit within the headboard. The general rule when measuring the height of the headboard is this: measure half way up the wall of the room where the headboard will be placed against. Your headboard should never exceed this height! Try to find a headboard that either reaches half way or down to a few inches below that point. This will prevent the headboard from "crowding" and overpowering the room.
