Jade balls heated with far infrared waves roll up and down your entire body as you recline, prone, on a Migun bed. In the demonstration center, you are welcome to lie down and let your woes melt away. Come every day of the week if you like free massages (around 20 minutes each), noon-7pm. The beds are for sale, but the only charge for visiting the center is listening to an infomercial. The benefits – like improved flexibility, bye-bye to back pain, and an energy increase – are a bonus.
