Very sturdy. So much more room for toy storage than I had imagined. The bins are double the depth of regular cubes. I could fit items from 2 if my other cubes. Easy to assembly, did it alone in an hour. Only issue, one of the outer pieces had 2 dents despite it arriving in too notch packaging to prevent damage. One quick phone call and the replacement piece is in the mail and on the way. The dents were minor and did not effect its function so perfectly functional in the meantime. Still very pleased with the purchase.
