The Barefoot Connections™ Bed Pad connects the body to the earth during sleep. It is placed at the foot of the bed over the bottom fitted sheet and tucked around the mattress so that the electrons and natural frequencies from the earth flow to the entire body via the feet and legs. Barefoot Connections™ Bed Pads are made of 50%cotton/50% polyester fiber (230 thread count) with embedded, conductive, inherently antimicrobial silver yarn.
