I have never seen or experienced a mattress with this level of support and comfort. If you wake in the morning with an aching back, this is the mattress for you. My husband has his own business and works some days up to 18 hours and his back is always giving him problems but just one single night on this mattress he said he could literally feel the difference. You will sleep like a baby cradled in the comfort of the amazing lushness of this mattress and its body hugging memory foam core and wake up from a solid nights sleep feeling refreshed and ready to start your day. It is infused with a cooling memory foam that you can feel working during the night to help keep you cool, and that is a huge plus here in Florida for those steamy southern nights. I have to say that this is the best mattress I have ever owned and I see a solid relationship with Serta for many years to come. Take it from 2 hard working people, get yourself one of these mattresses, you will not believe the difference in your quality of sleep.
