  • Far Infra Red heating units, which are integral to the cradle, emit gentle yet penetrating therapeutic warmth to ease muscle stiffness
  • Vibration Massage function is also integral to the cradle, with 12 vibration levels

    • Auto 1 mode changes both swing speed and vibration frequency 12 times per minute – lots of variation of swing speed between 83 and 119 and 9 levels of vibration frequency
    • Auto 2 mode changes both swing speed and vibration frequency 4 times per minute, and is more relaxing than Auto 1

    • Auto 3 mode is just for vibration and infra-red – the cradle does not swing. The vibration frequency changes 4 times per minute.
