We've only had it for a few days but so far it's great. I love a soft bed and this is soft. It came with a really nice cover that fits over the topper and my extra deep pillow top mattress. It does not shift around at all because it has a little weight to it and the foam is somewhat grippy where it makes contact with the mattress on the under side. My only complaint is a very slight odor (I'm picky). I think it will completely disappear.
