These are great sheets - if you have a mattress that doesn't requite deep pocketed sheets, like I have these will work IF you wash them in hot water, then dry them on the hot setting. They will shrink enough so that they fit the mattress nice and tight! I will say the best thing about them is that they feel so good and keep you warm, though not sweating. Now if you have to get up early for work - I would NOT recommend these - you will find that you will turn off your alarm and go back to sleep... I don't know why I waited so long to get flannel sheets! I bought two sets... I love the colors that are available. Oh, and my cat give two paws up!
