Electric sheets with multiple heating zones

Multiple heating zones

— the presence of multiple heating zones in a device allows for individual control over specific areas. This feature is particularly relevant for electric sheets and blankets (refer to "Type"), as other heating pads are typically not large enough to justify such division. The classic format involves two zones — for legs and the rest of the body. However, double sheets may offer different options, including two individual zones or four areas for both individuals. Regardless, zone division provides additional customization options. For instance, if only the feet feel cold in bed, focusing on the lower part of the electric sheet can save energy without heating the entire surface.
