I washed and dryed them four times since I got them, but they are no better than the first time.   They are VERY smooth, do not stay tucked into the mattress, and every morning I have to remake my bed.    In fact they are not long enough to turn down when making because they barely tuck into the mattress. Although rated for a deep pocket mattress (mine is only 12 inches), they just are too short.    I wish I could return them but I waited too long.
