This is a great topper! I have a firm mattress and need something that was soft and yet provided firmness so I wouldn't sink down too far. I have both hips replaced and this helps a great deal, I don't like soft mattress, so this was a great fix to that problem. Yes, the batting does tend to slide down the side a little, but that is easily fixed by just shaking it and pushing it more to the top. That is the nature of batting, so it's not an issue to for. I sleep comfortably and am happy with this topper.
