We created a patented designed pillow, with the help of top dermatologists, neck and back specialists and a chiropractic design to ensure the correct support for alignment and keep pillow pressure off your face. Sleep lines from other pillows over time can be permanent. Laugh lines and aging gracefully are what we strive for but pillow induced lines not so much. We also use CertiPur US certified foam so it is safe and harmless to you and the environment. As well as other unique enhancements to keep you cool when you sleep.
