We have two words to describe this product.............LOVE IT............ We are so happy with this product. In the past we purchased the four inch which we found molded us into the bed and as tossers we found it just a bit uncomfortable to make the indentation then sort of climb out of it to make another one. The one inch was just not enough for us so we purchased this one and just absolutely happy we did. Its comfortable, it does seem to stay cool, which we enjoy and found we are getting better sleep because of it. Being a cancer survivor I have joint pain and this is so comfortable I can not believe how well I sleep now. We are absolutely satisfied with this product, Overstocks online help and the shipping.
