When we received our unit there was a small crack/chip on one of the shelves. I contacted Wayfair and they stayed right on top of the problem offering to send a replacement piece or a percentage off. We already assembled the shelf because we were in some desperate need for some storage so we really appreciated the discount that they applied. Overall the piece is pretty sturdy, wish we nailed down the back piece a little better. Right now it is only secured around the perimeter of the piece. We should have done some in the center to keep it tacked down and not bulging a little when pushed on.
