This under blanket heater is the perfect device to keep you all warm and cosy as you sleep on those cold winter evenings. Manufactured to fit seamlessly onto a super king bed sized mattress, the electric blanket attaches to the mattress via the ties attached, and then all you need to do is pop your top sheet back over it and you’re ready to go. The blanket measures 150cm x 200cm and is manufactured from 100% non-woven polyesters. The beauty of this under blanket is that it features two control panels which lets you and your partner set your own temperatures, meaning you can compose your own perfect night’s sleep. Choose between the settings of low, medium, and high, and fear not of overheating, as the electric blanket comes equipped with an auto-shut off sensor that will cut the power if the unit gets too hot. The cable length stretches for 1.8 metres and delivers up to 60W of power on both sides of the blanket.
