It arrived in a very damaged box. Poor packaging. There was insufficient Styrofoam and the box was quite thin. The Styrofoam was shredded.
There were scratches on the black metal and two of the little nubs in the screwholes are missi g.
It is such a hassle to return it as it is very heavy and the box was not intact so I am going to live with it.  I covered the scraped spots which were now shiny black metal with black sharpie and I have a loose board that hopefully will be fine when books are on it.
The metal X bracing in the back is slightly too long (or the vertical shelves are too thin) so the braces stick out from behind each rail. If you are looking for quality... this is not it.  This was my first Wayfair purchase...I'm not sure I'll buy again especially for a major piece of furniture.
