I purchased this pillow to try and control my reflux while waiting to have surgery. I had developed severe asthma as a result of my reflux, and woke every morning in need of neb treatments and coughing. I had tried propping myself up with other pillows, and could never get comfortable. The first night I used this pillow was a God-send! I slept all night, no pain in my back when I woke, plus no coughing. I am now ordering a pillow for a family member with similar problems!
