Very heavy duty, which was what I wanted. Will not go together with the toy tools they give you with the frame. A ratchet will be needed. The hardware is designed to lock in tight when you screw them in, but because of that you cannot screw them in easily. Once we stopped trying to use the tool that cane with it and went to the hardware store and got the right tool, it went together without issue. It is high off the floor, so under bed storage is possible.
