As we enter much colder nights and seasonal family battles over the thermostat, you might be wondering how to save a bit of cash while still staying cosy. Enter: Silentnight's Comfort Control Electric Blanket , a fantastic choice for anyone looking to keep warm in a comfortable, cost-effective manner. It’s more true than ever this Prime Day, with this king-sized electric blanket down to £27.

60 from £42.99. If you have the king-sized version on the first setting - that's 28 watts - it costs less than 1p to run for an hour, meaning it's an extraordinarily cheap option and an easy pick over sticking on the central heating for an expensive one-hour blast.

The blanket, available in Single, Double, King, and Super King sizes, is machine washable, features overheating protection, and three heat modes to cover all bases. It heats up very quickly, too, getting up to temperature within just a few minutes.
