This pillow is really awkward. I think the position they have you lie in to use the pillow is what stops the snoring not the pillow itself. Note this position they require does not work well if you sleep with your head right at the top of the bed like most tall people do. This is a mammoth pillow. Using it craned my neck in a very bad way causing serious neck pain that required tylenol and a heating pad to alleviate. Maybe it works better for very large men who's body's (the space between neck and shoulder) can accommodate a large puffy pillow. I'm not sure who else this pillow would work for from an ergonomics perspective.
