The bottom is sturdy with a box spring + mattress. We actually managed to fit a full size mattress at the bottom and its used by adults. Now, the top is wiggly and the rail to keep children from falling is not tall enough. We lined up the edges with giant stuffed animals. With just the twin mattress, theres only about an inch of rail left. All parts were accounted for. My mom loves it.
Nice purchase
