I was very impressed with the Octaspring  Matress topper.  It is very comfortable.  I  have quite a firm mattress which I need for back support. Recently I had a fall and so needed a little more padding.  I was afraid that this mattress topper would be too soft, but was delighted to discover that it molded to my body shape and was both comfortable and supportive at the same time.  I love it and would highly recommend it.
