My son picked this out for his new bed. I first noticed that the comforter is quite thin, I'm going to have to add another blanket underneath for the winter. Secondly, the underside of the blanket is made from a different material that is silkier and every time he sits on his bed to play the comforter slides right off the bed. It also could be a couple inches wider, It barely covers the mattress and the top sheet hangs down a few inches below the comforter. Granted, I am pretty particular about making a bed neatly but there's no hope with this and a 3 year old. It would also be nice if they made extra pillowcases or shams that match to buy separately see less
