Beurer Heated Mattress Covers are made with luxuriously soft fleece and use ultra-thin wires, to offer maximum warmth and comfort. The Beurer Heated Mattress Cover is fully fitted with a deep, elasticated skirt which fits easily to your mattress just like a fitted sheet. The user-friendly, detachable controller has six temperature settings, including a pre-heat facility, as well as an adjustable automatic switch-off function which you can set for 1, 3 , 6 or 12 hours. Fast heat-up time enables you to feel the warmth in just 8 minutes, whilst low energy usage means that it costs less than 2p per night (8 hours usage) to use. Komfort heated blankets are machine washable and tumble dryer safe. Fully equipped with the Beurer 'Sleep Safe' automatic shut-off system, they also come with a 3 year guarantee - which means that you can have total peace of mind when it comes to both quality and safety.
