The bookcase came fully assembled which was AWESOME. I did read this in other reviews, but after assembling my fair share of furniture ordered online, this was such a welcomed bonus! The shelf is a TINY bit wobbly, but once you put some items with weight on it there is nothing to worry about. Some people commented that they didn't think it was sturdy enough, but I have to disagree. My shelf is holding a variety of heavy books, and I actually find that the heavier items are keeping the shelf in place. Would recommend.
