Read what the other reviewers have written about how hard it is to put together. The design is very clean and appealing. You will have to measure and drill your own holes on six pieces. I was careful but I still have a couple of shelves that don't mesh perfectly (about   1/24 inch off. Small but telling for me :-( . . . and I'm not a perfectionist. Also, maybe it was my 12 V drill but I couldn't get it to screw the long screws all the way in. I had to use my body weight against my hand screw driver to get all 16 screws flush (8 per unit).
One reviewer mentioned the less than robust finish. Believe it and be careful. With two people carefully assembling this unit, it would be easier and less fraught with potential damage.
Still, now that I'm done and my back muscles have stop spasming, I really enjoy the look.
