I’m really happy with this corner bookcase! It went together pretty quickly and is very sturdy. It comes with all of the necessary tools to assemble, but we quickly switched to a power driver to get it done faster. I don’t know if we started upside down or if the instructions were wrong, but by starting with panel 2 and screwing in the 14 rounds as pictured, once we got panel 1 on it did not meet up in the corner and we couldn’t line up 14 round 6. Had to undo it and start with panel 1 instead of 2 as pictured. That was the only issue but quickly resolved. Comes with many warnings to secure to the wall to prevent tipping over. I love this addition to my guest room.
