Very sturdy! I have three kids who are always in my bed and there is jot mivement or noises when they are playing on it. I put it together by myself in like 2.5 hours. Only problem I had was with getting the two top and bottom metal knobb looking connectors at the top of the bead and foot to go together tight enough but usualing a bigger allen wrench to hold it still while tightening helped. Now it's perfect.
