Each side of the double, queen and king blankets includes an individual controller, which features 4 different heat-zone options that operate simultaneously. For single and king single sizes, the controller is positioned on the right-hand side. For long single left (LSL), and long single right (LSR), you may choose what side you wish for the controller to be positioned. The controller allows you to set-up varied heat levels - even between your torso and feet. Sizes with controls on both sides may apply completely separate temperatures. Please note: This product cannot be shipped outside of Australia.
