Effect of firmness of mattress on chronic non-specific low-back pain
This is interesting, an a question I hear frequently in my office. Unfortunately, the answer is never easy and seems to vary based on the patient. I have a patient that used to work in R&D for Simmons company, and his company found that the firmness needed is dependent upon primary tissue involvement; i.e. muscle problem or joint problem. This would explain why different patients would respond differently to different mattress firmness.
