I bought these sheets because a normal set of sheets came off the bottom of the bed almost every day, and I figured if Tempurpedic can't keep a set on the beds they make then nobody can. These sheets haven't slipped off a single time. The straps on the corners keep it in place excellently. They're not the softest sheets, but that doesn't matter to me; however, that might matter to others. Overall excellent product, and I'm very satisfied that I bought these sheets.
