Ordered this bookcase in Dec 2019. Wayfair delivered the wrong color but they managed to make it right within a week later.  It was easy to put it together thanks to the instruction. The back of the bookcase is made of cardboard and very flimsy. I accidentally ripped a corner while assembling, so be careful when you do it. The bookshelves are sturdy and each of them can handle about 15 lbs. So far I am satisfied with the purchase.
