Our mattress had body depressions and was very uncomfortable. I purchased this topper because reviews said it will turn old mattresses even with body depressions into a comfortable mattress again. Well, that was not the case for me. We still had the depressions. We did get our mattress replaced under warranty, so the topper is comfortable and I do like it; however, we have a high bed, and it added 4" to that height! I never thought about it making that big of a difference, so we now it's a little harder to get into bed-no falling into bed for us! Overall, it makes the bed softer-but not too soft.
