"I love my Biomat. I sleep on it all night. One hour at the top red and the rest of the night at one yellow. It has made HUGE changes in my health.My hands and feelt have always bothered me. Even with elevating them all night they would still be swollen every morning and would just get worse every day. Now- I wake up with my bones sticking out - like every other person. By the end of the day I may have some swelling but nothing like it used to be. I also have both hips replaced and a triple back fusion. The Biomat makes a HUGE difference in my pain level - pain free. LOVE IT."
