If you often feel back pain, it may mean that your body needs more intimate care. Pick the right firmness mattress to keep your spine position in a naturally relaxed and aligned state while you sleep for better support and pressure relief, so you can move freely in the new day. When lying on your back, your spine should remain in a natural S-shape, and when lying on your side, it should remain horizontal and straight.
