Although you probably had to buy your mattress and box spring separate from the headboard, if you purchased a bed frame for your bed chances are the frame came with a headboard as well. Sometimes this is not the case, and at times you may wish to buy a nicer headboard for a frame that you already have.
When looking for a headboard, it is imperative that you take accurate measurements. This is to ensure that the bed fits snuggly against the headboard; if it is not a good fit, then you will undoubtedly be disappointed with its appearance. First, diligently measure the width and the length of the bed frame. Once you have those measurements, then measure the height of the bed (including the mattress in the frame).
