Mattress that Gives Support to your Bones

I am really intrigued by this memory foam mattress. What kind of mattress is this really? To satisfy my curiosity, I googled it and found a site dedicated to selling this kind of mattress. Hmmm interesting! It says in the website that I get to sleep fast, I get a satisfying sleep, there is pressure relief the moment I lie down, the mattress conforms to the shape of the body thus support bones. There's a lot more advantages when you get to sleep in this mattress. I think I need one!
