Extremely happy with this corner shelf, in my opinion was very easy to put together and the shelves are sturdy and have a good thickness to them. Pieces did not have any knicks or scratches,  all pieces packed tightly and protected in the box. Was a bit weary after reading some reviews of issues with attaching the top shelf, but was actually very easy and quick to put together. There is no gap at all on the top shelf. A tip, pay close attention to the particular details pictured on the frame pieces in the instructions. Very happy with my purchase!
