Adjustable Orthopedic Neck Pillow for Stomach: To prevent stress on the neck and spine, stomach sleepers need a different type of pillow. For stomach sleepers, a low-profile orthopedic neck pillow with adjustable height allows the head to rest comfortably without being overly elevated.​ The softness and hardness of the pillow should have a certain amount of support, be able to maintain a certain height, provide proper support for the neck and head, and have a slight elasticity.
