Back Sleepers
Pros: Many doctors agree that back is best. Snoozing in savasana pose is a boon for spine and neck health, because the back is straight and not forced into any contortions. Plus back sleeping helps the mattress do its job of supporting the spine. In a perfect (and kind of uncomfy) world, everyone would sleep on their backs without a pillow, as this position leaves the neck in a neutral position. Using too many pillows, however, can make breathing more difficult.
