First of all, I have read the information on how to buy a mattress on this forum and I have narrowed my purchase to a latex mattress from one of the companies that are members of this website. I have fibromyalgia as well as a bad back & neck–having had several back/neck surgeries. I know that everyone is different, but considering the fibromyalgia, what firmness have others found provides their best comfort? Thanks for any input, and I hope any Americans on this forum have a great holiday! Nancy
