Pretty big, bought it for my mother who is 5'3 100 lbs soaking wet and it was big for her, takes up a good portion on a king bed, but I bought it for her for her chronic lower back pain. I'm a nurse and we keep people off their backs after back surgery to promote healing and it can help support the back when you want to lay on your side and help with muscle spasms. Don't know how people use this for GERD, but I can believe it; this pillow was just huge, totally soft but big!
