A Supportive Bed Frame: Elephant in a Box Bed Base The Elephant in a Box Bed Base ($399) has a supportive accordion style base than expands when you open it. All you have to do is then attach the side panels and the top cover. My favourite thing is that unlike other easy-to-put-together furniture, it's actually easy to take back apart, too.
