I bought this at my husband's request as he found our mattress to be too firm. It's soft and comfortable but difficult to keep in place. I'm constantly reaching under to pull it back to the center of the bed. The last time I tugged it I pulled an edge right off. I'd love to see it encased in a cover that's anchored to the mattress so that it doesn't move. As it is it lies on the mattress and a silky type cover (like a fitted sheet) just goes over it. I think there must be a better way to anchor this pad.
