I have always had back pain in the mornings. I have spent a lot of money on different mattresses and none of them seemed to be able to fix the problem. When I first saw this product's description I was rather suspicious but the cost was nothing comaring to what I have spent already, so I went ahead and ordered it. Let me finish this review with this sentence: " I am still surprised, after near 5 month of using this roll, that I did not have back pain even a single time when I get up in the morning!"
