The Ecologic Beurer heated underblanket is made from naturally soft 100% polyester for maximum comfort. Unlike other entry level heated bedding, the Ecologic range is generously sized to fit and heat across almost the entire length and width of the bed. It has been designed to use low amounts of energy, whilst still providing a great amount of warmth: making it both economical and kind to the environment. The blanket also features non-slip tie-down to ensure a perfect fit to your mattress, along with a controller with three temperature settings and a power light indicator. It is machine washable and tumble dryer safe, as well as being suitable for all-night use. The Ecologic Beurer heated underblanket also comes in a Double, as well as a Single.
