Designed for all seasons, our quilted electric blanket has an 80 GSM fill that supports warmer sleep in winter and cooler sleep in summer. Further, it has a removable mattress topper complete with a zip. Each side of the double, queen, and king blankets have individual controllers that feature 4 different heat-zone options, which operate simultaneously, whereas the controller is positioned on the left-hand side of the single and king single sizes. One side may be set-up with varied heat levels between your torso and feet while the opposite side may use different temperatures. Long Single: Controller Options With the size options of Long Single Left (LSL) and Long Single Right (LSR), you may choose which side the controller is positioned on. The easy-to-read LED display is designed for dimly lit to dark rooms while the control unit features 9 heat settings and an easy-to-set timer. Being machine-washable, the quilted topper can be removed for quick, easy laundering without removing the wired section or controllers. The 50cm fitted skirt will fit over larger modern mattresses.
