I had high hopes for this mattress topper when I read the reviews. I have another 3-inch topper that is just wonderful, and it actually didn't get as good reviews as this one. However, this topper was a bit of a disappointment. I got the King size, and after about a month, it still hasn't "relaxed" enough to cover the bed from edge to edge, so I have to assume it probably never will. It's about 3 inches short of fitting the mattress from side to side. Second problem is that the foam doesn't regain its loft after you get up in the morning. Deep impressions remain from the heaviest areas of the body, which creates a very lumpy surface if you want a nicely made bed. While reasonably comfortable to sleep on, this is a very average topper at best.
