As others have said, "Like sleeping on a cloud!" My wife has had two major back surgeries and we have been through countless mattresses and memory foam toppers without success. Recently, we bought an Ikea extra firm mattress, which offers great support good, but is way too hard. This topper did the trick, providing just enough cushioning so that are both comfortable. We have found that fluffing it each day works best for us. It's WONDERFUL!
