Acid reflux pillows help people who suffer from this painful disorder be able to sleep comfortably and awaken without painful burning in their chest- or worse. I've been rudely awakened in the middle of the night with an incredibly painful burning sensation in my throat, with acids almost coming up from where they shouldn't. Disgusting and pretty scary too. If you've gone through this too, and your doctor has told you that you have acid reflux, or GERD, then this pillow may really help you.
