As the human body is in constant motion for much of the day, it needs to be adequately supported while it truly rests during sleep. The mattress has an important role in this and should provide uniform support from head to toe while distributing pressure evenly across the body to help circulation, decrease body movement and enhance sleep quality. A good mattress gently support the body at all points and keeps the spine in the same shape as a person in the standing posture. This is critical as our spine has a natural curve and has the opportunity to align in a healthy position during sleep. Improper sleep postures are a major cause of body pain and restless sleep. According to doctors, sleeping on your back is healthy for the spine as it is in this horizontal sleeping posture that the spine has the best ability to align itself naturally
