It seems pretty sturdy but
"It seems pretty sturdy but a few of the pieces had some noticeable dents. This seemed to be caused by lack of cushioning material on one side of the box. We were able to assemble the bed in a way that kept damaged parts against a wall, so it isn’t noticeable in our room. Just disappointing. This is also one of the more frustrating furniture assemblies I’ve done. The instructions were clear enough, it’s just the method of assembling the loft bed frame was very difficult for two people."
