I have so much regret about buying this blanket. I have a deep mattress (nothing extreme, deep pocket sheets fit fine) and the blanket was not big enough to cover the sides of the mattress (it came down about 3/4 of the depth of the mattress). It also came with some smudges (white blanket) and a big snag, but I thought maybe it would just wash out so I didn't send it back. I washed the blanket on a delicate cold cycle and tumble dried low- the smudges came out but it shrank so much now it basically only covers the top surface of the mattress. It looks so stupid and I get frustrated every time I make the bed.
