I have been using the Adjustable Spine Alignment Pillow for about 6 months now. I love it! I used to have restless night sleep always tossing and turning. Waking up with a crick in my neck. I have been sleeping better than ever since I started using the pillow. I did need to adjust how much padding to put under my neck. It took a few tries to get it just right. But that is the beauty of this pillow is that it is adjustable. When one of the neck pockets gets padded down I just add a little more filling. I have only have had to do it once so far and its really easy. I would highly recommend this pillow.
