And thanks to the sustainably sourced organic 200 thread-count cotton, it's warm in winter and cool in summer, so you can use it as an ordinary mattress protector all year round. Check that the control unit connector (2) is fully inserted in the mattress protector connec- for (1) and reinsert the plug in the socket (3). For continuous or all-night use of the appliance set the control unit to temperature levels from 1 to 3 only. Enjoy tailored warmth on both sides of your mattress, with the choice of one or two detachable controls.

Each one can be used independently - perfect if your partner runs hot and you run cold, or vice versa! The cotton percale is breathable and it will keep you cool and fresh during summer months, with the added benefit of switching on the heat when feeling cold.To set the control unit to the continuous use temperature, press the temperature selector button (8) until LEDs 1, 2 or 3 light up (11). Browse through our range of top brands like Dreamland, Slumberdown, and Silentnight to get the best quality for all budgets. Even better, the natural fibres keep you toasty in the winter but cool in the summer, it’s simply mother nature with a welcome warming boost.

The Dreamland Boutique Heated Double Mattress Protector is made from high quality cotton percale with a 200 thread count. Each side of the blanket runs at 150W on full power, but the precise cost will depend on how how long you use it for, as well as your current energy tariff.

With six temperature settings to choose from, including fast heat-up, Intelliheat+ technology ensures your bed is warm in just five minutes.

Choose the level of heat that suits you best from the six temperature settings on the easy-to-use Intelliheat+ controls – with a handset each there’ll be no need to fight with your partner over how cold their feet are – and no need to roast all night long if they feel the cold more than you do.

I tested Dreamland's Snowed In dual-control heated mattress protector, one of the best-reviewed electric blankets on the market, scoring it on performance, features, style, product care and value for money. For use, cleaning, maintenance and storage of the appliance, please follow the instructions specified in the corresponding chapters. In terms of running cost, while the Snowed In heated mattress protector is widely advertised as costing "from 1p" to run, this is a fairly meaningless figure without further information.
