At long last I have book shelves for my large health-book library in my office. I couldn't beet the price, they are solid wood, were easy to put together and customer service was a dream when I needed to have a replacement sent. This single purchase has sold me on Wayfair. 
The shelves are a little light for the work load I have them for, and there was some fright damage. The price was excellent and they are a big improvement over what I had.
