A firm mattress may help alleviate back pain by distributing the body’s weight more equally and supporting spinal alignment. This may then help improve sleep quality. The National Institute of Neurological Disorders and Stroke recommends sleeping on a firm surface to help prevent back pain. A review of studies on mattresses and low back pain concluded that a medium-firm to firm mattress can promote comfort, sleep quality, and spinal alignment.
