I bought this product for my Dad who has been struggling with acid reflux. It used to wake him up at night semi-choking, so I did some research on wedge pillows. I chose this one because it appeared to be high enough (at 7 inches) to help, but not so high as to be uncomfortable. He says he quickly adjusted and doesn't even feel like he's sleeping in a raised position. He likes to put a fairly flat pillow at the top and it feels natural to him. He can also sleep on his side comfortably, too. The wedge core is firm enough to maintain the angle, but has a memory foam outer layer which makes it cushy. Most importantly, he says he can barely feel the reflux now, if at all, and sleeps like a baby. Everyone has different circumstances but for those struggling with reflux and getting little relief from medicinal aids, it's definitely worth trying the wedge pillow. My Dad got his sleep back.
