I purchased a 5 shelf book case and turned it into a closet for my baby. It took me about 30 mins to put it together and another 30 mins to screw in the closet rods and figure out exactly where I wanted the shelves. I had so much fun hanging up his little clothes.
WARNING - please make sure case is secured into the wall to prevent children from knocking it over. Many have died by furniture falling on them. Please secure them
