For months I had knee and hip pain because of a bad back. We had gone as far as buying top of the line mattress with no improvement for my back pin. After purchasing this memory foam topper my back pain starting going away little by little every night and now I have wonderful painless nights sleep. My husband and I love this memory foam. When we lay on it you can really feel your body relaxing. I feel it massages me. Plus since there are different layers on the memory foam targeting specific areas of your body as you lay on it, it helps you even more to relax. Again we are very happy with it and recommend it.
