I just got a bed from walmart online. It is the memory foam layer(3"), then an air cool layer(3") to solve getting hot and then a (6") firm layer for support. They sell for 500+/-. We also got the frame made for that bed. I went from 1-1.5 hrs to fall asleep to 30 minutes..... Just check out WM online and it is the one with a few thousand reviews and 4-5 stars.
