Query: disapointed

I bought these for my daughter's room, but they would not stay put, the bed fell a few times and scared her and the wood cracked and broke. These are sturdier than those plastic ones (those broke). She is very thin, was not jumping on the bed or anything like that. But you cannot move the matress too much to make the bed, unstable. They are in the garbage.
