This is a heated mattress pad from Serta sized for a Twin XL bed, 39 by 80 inches, made of white polyester microfiber. It warms the bed from underneath the sheet, so the heat reaches you directly rather than through a duvet. The microfiber surface is soft and the pad is machine washable. It suits dorm beds, adjustable bases and single sleepers in a long twin, and it competes with heated pads from Sunbeam and Biddeford on warmth control and fit rather than on extra features.
