Ladder is held on by hooks with tiny wood screws. I'm sure it's enough but feels like it will give out. Would be better with a bolt through it. Drawers did not get built because I would have had to figure it out on my own for where to mount them. Wasn't much of an issue as I didn't want the drawers anyways. The wooden slats are too flimsy. Thinking of putting a piece of plywood down  instead of those slats. Have to be careful that the kids don't bounce on the bed, they will break.
