I LOVE this pillow! My chiropractor purchased me one through my insurance. I have chronic neck pain because my neck spine grew in the wrong direction. I prefer a high pillow but that's terrible for my neck...this pillow has four positions, all are a perfect height, even for me. My neck & spine always feel aligned! I never wake up with neck pain & cranks in the morning. This pillow changed my life! I tell everyone about this pillow!
