Before ordering I asked them if the cabinet was strong enough for books and if the shelves were adjustable. They assured me it was and when  it arrived I could tell at first glance that it was a strong piece of furniture. 
My husband and I put it together in about 3 hours without any trouble.
It's just what I was looking for. The finish looks good except the shelves could have been stained a little better and edges protected in shipment better. But since the shelves are inside the cabinet and will be covered with books, it will be fine for our purpose.
I would order this cabinet again and order from Wayfair in the future. 

Pros: Easy to put together. 
Cons: Shelves could be stained better. Examples of stain color weren't very clear. Cabinet darker than sample picture but didn't return it because the lighter sample picture looked too light.
