I love wayfair over all, but I was really disappointed with this purchase.  The first thing go noticed when I unpacked it was that it’s not really ‘white’, but more of an off white/ivory colour, so it doesn’t blend in with the other furniture in the room. (My bad for relying on the online photo.) the little plugs for the screw holes are a proper white however, so they don’t even blend in, and just look silly. What was more disappointing is the abysmal quality of the book case. As people have said before, it’s quite sturdy and easy to assemble, but my bookshelf arrived dirty and marked (which took a lot of scrubbing to clean, and still won’t all come off) and even then the edges look messy and ragged where the melamine finish has been glued together. It would probably cost more to ship it back than the bookshelf is worth, so not even worth returning. 
I’ve been happy with all my other purchases from wayfair, but this is one supplier they should stop stocking.
