My friend with chronic low back pain raves about her new body conforming mattress. Is it possible that it could make that much of a difference?

Many people report advantages or disadvantages of specific mattresses. A recent study using 120 subjects suggests that body conforming mattresses can improve back symptoms, function, and sleep. The dropout rate was lowest among those using the body conforming mattress versus the other two mattresses studied, indicating it is also well tolerated.
