I have had lower back pain for more than 30 years. The best mattress that I would recommend is a Beauty Rest and make sure that is is the firmest one that you can get. I have used and replaced this same mattress for years and it has been so supportive to my back. I can tell that I may need to replace the one I have in a year or two. I think that they are top of the line, but I would never buy any other brand than Beauty Rest (firm!). Hope that this helps.
