When you sleep face down, your neck stays in full rotation for 7 to 8 hours, forced to one side with the weight of your head on it. No pillow can fully correct this. It's the position most likely to cause neck stiffness, nerve compression, and morning headaches.
Our Align Pillow is designed for side and back sleepers. We'd rather be honest than sell you something that won't help. That said, many of our customers were former stomach sleepers who made the switch, and they're glad they did.
