Stay warm this winter with our reliable super snug cotton covered electric blankets. Created with warmth and comfort in mind, these electric blankets have a dual control and come encased with a luxurious pure cotton sateen cover with a classic self stripe. An electric blanket consists of three main components: a specially woven cloth called the shell; the heating element, in the form of insulated wire; and a bedside control and power cord. The shell is a blend of polyester and acrylic which has been formulated for the industry. The wiring is a positive temperature coefficient material that is heat producing and heat sensitive along its entire length and is encased in an insulated jacket made of a proprietary blend of plastic. The bedside control and power cord are made of a combination of plastic and metal materials.
