I'm glad you got your new mattress, but so sorry about your weather.
ABout 3 years ago we spent a bundle for a queen size top of the line Sleep Number bed. We love it. It has an adjustable base so you can elevate the head or foot. That was a God send when I had pneumonia last year. Also when my husband tore a muscle in his leg. You can also adjust the firmness of each side with the touch of a button. It has two air-filled bladders inside, topped by memory foam, then all zipped into the casing. If a part fails, or the foam breaks down, you just replace that component rather than the whole mattress.
On the other hand, the initial cost was an arm and a leg.
