A tuckable electric warming blanket for patient warming and a method of using such a warming blanket. The blanket may be used to warm the lower body of the patient or other portion of the patient's body. The blanket may include one or more rigid stays that extend along the right and left sides of the blanket. The stays assist in fully tucking the blanket under the patient and reduce the potential for bunching up the heating element under the patient. The blanket may also include a flexible, unheated foot portion that is tuckable about the patient's feet.
