This bookcase just arrived in time to be filled from a move. I wanted a "real wood" bookcase and I got it. I'm so tired of buying cases that end up being more like particle board. It was packaged quite sturdily, and once the restraints were cut, it easily opened up to its full position. There are protrusion at the top which allow for stacking. The only question was which of 3 areas will this bookcase go. Thanks Wayfair for making it EASY for me to find real wood furnishings.
