I am adjusting my review because after one day in my office with two hardcover books leaning on the left side support, this bookcase is completely slanted. I double checked all screwed to make sure they are as tight as possible. It's just a poor design for construction. The top two shelves are attached to a side support that is only connected to the base by two dowel rods. It is very wobbly even though it looks nice from a distance.

Should not be used to hold books or anything with weight. The books leaning in the photo would not be possible as it will cause the whole bookcase to lean under the weight.
