The Airsenz Comfort Fleece King Size Electric blanket is a luxurious, comfortable fleece electric blanket that fits like a fitted sheet onto the mattress, using a deep elasticated skirt, ensuring no movement of the blanket and pure luxury when sleeping. With 9 heat settings and a 12 hour timer, you can set the electric blanket to the levels of heat and time that suit you. The timer is the amount of hours you would like the electric blanket to be warm for. You can also set the body part of the blanket to a different heat level to the feet, helping users who suffer with poor circulation or cold feet. Each controller (dual controls) controls one half of the bed, so each user can have completely different settings and even one user can have the blanket on and the other turned off completely. The soft, arctic fleece provides a warming, relaxing and luxurious material for the perfect nights sleep. Machine washable and easy to fit. 2 year warranty period.
