Ask 100 people and you will get 50 different answers. Buying a mattress is truly one of those personal tastes (like buying a specific shoe for sore feet). Back, side, or belly sleeper? Type of back problem?
Nothing to get the root of, my wife has scoliosis. She insists on getting a new bed.
Have you thought about going at it a different route and maybe looking into getting a specialty pillow?? It's a MUCH cheaper option and may provide you the same benefit as a new mattress.
See above.
