This bookcase arrived in two boxes. All parts (even some extra, thank goodness) arrived with an ease to follow instruction sheet. It's extremely sturdy, and we especially liked the wall fasteners that the company strongly suggested. The shelves adjust easily. I do wish there were stickers or plastic inserts to cover the adjusting shelf holes, just for a cleaner, finished look. Wayfair is a fantastic company to order from and work with. Excellent customer service, every time.
