I have had three major back operations over the past twenty years and have since then tried to find a sleeping surface that could help relieve the pain I woke up with every morning. Visco Pedic changed all that. Since using the Visco Pedic Memory Foam Overlay and pillow I no longer wake up with the pain and aches I used to. What a fantastic product, my only regret is that I have not discovered this product decades ago!
