Have had these sheets for 1.5 years. They fit great with extra room on the flat sheet at the bottom to tuck in. It stays farily well, but will pull out occasionally if you raise the foot of the bed very often without retucking. I love the a loose fit on my feet when I sleep., and it still will remain tucked. Its nice to have the room in the zeroG setting, too. Love the fit of the bottom sheets, snug and stays on perfectly. Would like a softer feel to the touch, but love that they are 100% cotton. Would buy again.
