This bookcase is just awesome!! It's the 3rd one we've purchased for my daughter. She wanted the 4 shelf to go along with her 5 shelf and 3 shelf bookcase and has them arranged on one wall in a stair-step pattern. It looks so amazing with all of her books arranged in them. It assembles quickly with just a screwdriver and hammer if you want to apply the back and is very sturdy. Love it!!!
