I was having back trouble and my chiro told me that my mattress was likely to blame. I bought this mattress on a whim hoping that it would be good, and it was great! I went to my chiro again and she said that whatever I bought has improved my back very much. I couldn't believe that my Tempur Pedic was the reason I had a bad back and that this mattress actually was better for my back than the 3200 dollar mattress I had.
