During testing, we didn’t notice any cold patches and our co-tester appreciated that they didn’t need to have their side switched on as the dual controls allow each side of the blanket to be adjusted independently. With 10 heat settings and 10 timing options, plus easy-to-use controls, the Slumberdown elegantly warm luxury heated throw was a no-brainer to win best overall for this roundup. In fact, it’s the perfect answer for those of us who are style conscious and want a throw that looks great draped over the sofa.

This means that our expert tester put leading brands to work, making up a double bed and measuring how evenly different settings distributed heat and whether they fluctuated over time.One charge of the blanket should last you between 90 minutes and three hours, depending on how high you have it whacked. The king-size measures 150 x 144cm: comfortably covering the average dimensions of a mattress apart from the pillow area (4ft 11in x 6ft 6in or 150 x 200cm). The single control has six heat settings and we tended to whack it to six to prewarm, and then turn it down when we were under it. You should wash your electric blanket approximately every few weeks to once a month, or whenever the blanket gets dirty.

Plus, there are nine heat settings, including for your feet, and the under blanket design fitted securely to our test mattress.This under blanket’s accompanying app means you can turn it on while you’re out, leaving you with a warm bed by the time you’re back. Dual controls were also assessed, as was the accuracy of each heat zone to see if warmth leaked over from one side to the other when set to different temperatures.

There’s no timer, however, so you’ll need to remember to switch it off, or it has a nine-hour auto shut-off.

The heat zones weren’t as well-defined as others tested but the soft blanket fitted our mattress well, although the edges did start to curl a little after washing. But what we particularly liked about this heated throw was how easy it was to use, despite having 20 settings. It’s made from microfleece, which makes it soft to lay on all night and cushions against the feeling of the wires. Another plus is that it’s machine-washable at 30°C and tumble dryer-safe thanks to the detachable control, and comes in a reusable zipped storage bag. The controls are easy to use, with six heat settings – including a fast-heat setting – and three options for the auto shut off duration.
