Tempurpedic mattress is the BEST choice! When I was looking to buy a memory foam mattress due to a recommendation by my chiropractor and my doctor thanks to arthritis, bulging discs, and many other health problems. When looking and comparing Tempurpedic was SO expensive. I finally convinced my hubby that I needed a new bed, we went to a furniture/bedding/appliance store. They had tempurpedic beds there so he could feel the beds. He nearly had a cow, when I picked out what I wanted and he saw the price. I wanted the king size bed, with the double bases. I convinced him to go with a queen size bed and the tempurpedic base. However, the salesman convinced him that Sealy's version was just as good and that is what he agreed to get. I wish to this day that we had spent the extra money.
Tempurpedic has an amazing ability to still support your body even on the edges of the mattress. The sealy version does not, and when you get close to the side of the bed, you feel like you are falling off.
Good luck with your choice!
