As a physical therapist and user of this product, I find this to be one of the smartest things I've seen on the product for keeping people's head, neck and upper back in Great position long-term. I think that this is a product that is long overdue in the industry! Personally, this is one of the things that is helping me recover from neck surgery one month ago, and I am grateful to have it in my office and happy to recommend it to others
