My doctor recommended a wedge pillow to help with my reflux so I purchased one that was 7" high for my primary home. It took a while to get used to and I find that I tend to slip down the pillow during the night thus loosing the benefit of having my head raised. I needed to purchase a second wedge pillow for my vacation home so I chose this Beautyrest 5" high pillow to see if it worked better for me. It definitely makes a difference - I stay centered on this one. The wedge pillows have definitely helped with my rellux for anyone that is skeptical about purchasing one and based on my comparison the lower height pillows are more comfortable to adjust to.
