My hip has been hurting from the pad that I HAD........I bought this and it is wonderful to sleep on....very picky person.  Love this pad, I would recommend it for back issues......love it......came fast.  No more sinking in the bed.......BUY IT, BUY IT.........YOU WANT REGRET IT.......I am 74, feels great and my back feels good in the morning and while sleeping.......finally got some rest.......:):):)
