Take away the winter chill with our dual controlled, superior quality electric blanket. With soft 500gsm polyester material & fast pre-heat, this superior electric blanket offers a smooth surface to sleep on & allows you to warm up safely on cold nights. The low, medium & high heat settings can be selected with the two controllers, giving you and your partner separate temperature control over your own side of the underblanket. Bed ties & loops are also included to allow for secure fitting to your mattress. Please note, the Double Size Superior Quality Electric Underblanket is not designed to fit edge to edge on the mattress. Pre-heat for a warm bed & switch off before falling asleep or with the temperature set to low, the electric underblanket can be kept on continuously throughout the night to maintain the temperature. Overheat protection is builtin to automatically shut down if too much heat is detected as an added safety feature. To wash, remove the detachable cord & controllers & place in a wash bag in any standard washing machine on a setting of 30°C. Once clean, leave to air on a clothes line & always ensure the product is fully dry before using again. Conforms to the UK's highest safety standards, EN standards.
