Electric blankets are bedding items designed to provide warmth through built-in electrical heating elements. They typically consist of a soft fabric layer with insulated wires that distribute heat evenly across the surface. Users can adjust the temperature settings to achieve their desired level of warmth, making them popular during cold weather. These blankets are often used for added comfort while sleeping or relaxing. Safety features, such as automatic shut-off timers and overheat protection, are commonly included to prevent accidents. Electric blankets can be found in various sizes and materials, catering to different preferences and needs.
