I bought 4 of these bookshelves instead of constructing built-ins, as I was burnt out from home renovating. The shelves look GREAT and fit together well. Assembly was a breeze--far easier than I expected! I had a woodworking guy out to do some trim work (not on the shelves) and showed him the finished product; he said he thought they were solid wood, and he is not easily fooled. Shipping was also fast and problem free. Thanks, Wayfair, for another successful delivery to my home!
