If I could give this zero stars, I would. Cheap, cheap, cheap product. I spent almost an hour trying to do step one (attaching a shelf to a side), but the bolt would not go into the attachment after attachment was inserted in the hole. When I finally got it in enough to start to tighten it, the shelf cracked. I'm out about $120 (since wayfair's policy is to have to drop the item off at a UPS depot for return...I don't have a car, and can't get there with the pkg). Avoid this one at all cost. Pay more and get something that has a bit of quality.
