Hi ben, I think the problem might be that the dowel has come out or not been in the frame had this with mine. if you look there is a hole in the frame where a peg/dowel should be. Also a hole in the footboard for it to go in to stop it rocking. Its only on the right side. I put in a metal type spring dowel in mine. maybe someone else might be able to explain it better . but check yours anyway I might be total wrong matey atb geoff
