My husband thought Easy Rest would help our backs and our previous mattress was already 20 years old so we bought one. Their sales representatives were great. They were able to answer all of my questions and demonstrate how to use the bed. I like the bed and I use the vibrator but when I turn it on, I am not sure if it is supposed to make my head vibrate, too. My husband props the head part up because it helps him a lot with his bad sinuses that make him not breathe when laying flat. He doesn't cough much and I sleep better with Easy Rest.
