I have been coping with back and hip pain for two years and realized it was my 8yr old memory foam mattress, after traveling and sleeping in hotel beds for a period of time. I decided to shop for a new bed and tried about two dozen mattresses. This particular mattress was like resting on a cloud in the showroom...and after the first night sleeping on it at home, I woke up with no back or hip pain. Now, about a month later...still pain free!! I didn't love the price, but overall worth the investment.
