What type of mattress is best for chronic low-back pain?

Answer:

There is no single mattress that's best for everyone. However, a randomized clinical trial involving adults with chronic nonspecific low-back pain found that people assigned to a medium-firm mattress had better outcomes for pain in bed, pain when getting up and disability than those assigned to a firm mattress. Individual needs can vary based on sleep position, body type and the cause of the pain.
