We were hesitant to purchase, because of the cost. But, with the back pain my husband was having constantly, we figured it would be worth it. And it definitely was. My husband's back used to sink into our old mattress. With the Tempurpedic LuxeAdapt Firm he is not having the back pain at night anymore. In fact, during the day when his back starts to hurt, he goes into the bedroom and rests on our Tempurpedic. He absolutely loves it.
