I would make sure that you figure out what size of bed you want. Sometimes a queen and a full size take up the same space. It is just a matter of moving the rails out, but generally make sure you get the size of bed you want, because if you buy a nice set, you are probably going to have it a long time. Later on down the line, you do not want to be disappointed, because you may wish you had a king size bed, but all of the furniture (headboard, footboard, rails and everything) matches only the queen. Think long-term, that you're probably going to have this furniture a long time. Make sure you match it to the size of the bed that you are going to buy.
