Totally assembled and REALLY good quality! (I am beyond picky FYI!) 
Probably the best wayfair piece I’ve ever purchased!! Looks like an expensive Zgallerie credenza!
It’s much heavier than I expected, and the picture makes it appear taller than it is. But of course the measurements are correct. I just thought the photo on the site was a bit deceiving. 
Overall, I’m SO HAPPY with it and LOVE everything about it!! Definitely recommend this one!
