I love these. My old overstock sheets were very good for about 3 years, but then ripped at the seams because my mattress is super thick and they really had to stretch to fit over. These are enormous, which makes making the bed super easy - and they havent slipped off the corners once since I got them last month. Word to the wise, though - if your mattress isn't super thick, you probably don't need these. Oh, and they are very thick and heavy, which you might not like in summer if you're attached to also using a blanket.
