The Bio-Pulse bed has 2 pulsing magnetic coils that are mounted on soft foam and housed in a handsome reversible navy to stone gray fabric. The pulsing magnetic field easily penetrates into sore joints and muscles, providing relief of painful conditions. There are three pulsing frequencies. The rechargeable power control unit provides 30 minutes of therapy and then shuts off automatically. This is a very convenient method for you to be certain your pet gets his therapy each day, without any effort on your part. Thanks to Gabrielle "love girl," for modeling.
