These shelves are more complicated to install then they need to be. Also, they don't show that the bottom pieces that you must put up to bolt into the wall are UNPAINTED wood and look very tacky. Didn't even attempt to put them up because they would look so bad.  Went to return this item - (I bought three). Worst part is that I just found out when you return an item to Wayfair they still charge you the shipping. Looks like it will be my last Wayfair order!
