I couldn't be happier with my unit and how much it has helped me in my quest toward wellness. The VASL has helped me sleep, and decreased anxiety that I suffered from for many years. I has helped me with chronic pain I suffered from for many years. I love that my grandchildren use the bed to decrease their anxiety as well as friends and other family members that can't get enough of this multi-dimensional experience in sound and vibration. Thank you Holistic Health Science peeps! I love my VASL!
