Easy to assemble, surface seems to be smooth, the edges/corners are not worn. The color is to a bit too dark to my liking, very deep brown, nearly black. Also, the top surface of the very top shelf has no polishing, it's just the bare engineered wood. That doesn't really matter if you are not too tall and don't look at the unit from up above. Otherwise, you would need to buy a decorative paper sheet of the matching color to cover that side (that's what my wife actually did).
I was looking for a corner bookshelf that had some curve to it to counterbalance the rectangular credenza it would be located near. So glad I chose this bookshelf! It is very attractive and has a little more visual interest from the usual boxy bookshelves I have located in other parts of our home. Assembly was pretty straight forward. My husband and I put this together in 45 minutes and that included him running to the garage to change out drill batteries during assembly. It is definitely easier to put this together with two people and I recommend using a drill instead of a manual screwdriver to put in the screws to speed up assembly time.
