Durability After testing, each electric blanket and heated throw is washed and dried five times to simulate wear and tear. We then conduct a full electrical safety test on each one. None showed significant wear and tear, and all passed the test. As part of our test, we washed and tumbled dried each of the blankets five times after testing, and then conducted a full electricity safety test. All the blankets passed.

Comfort A panel of five volunteers assesses each electric blanket and heated throw for comfort. There is quite a big difference in how snuggly each one is and underwires are more noticeable in some of them. For electric blankets, we also assess how easy each one is to attach to a mattress and how comfortable each one is to lie on under a fitted sheet. If you buy your blanket from a reputable UK retailer, as we did for our tests, then it should be safe. Before getting started, it is important to know that using a electric blanket is not recommended if you have certain health problems. More detailed information can be found in the instructions for use. Using a heated underblanket is harmless if you are healthy. On the contrary, heat can promote circulation. Heat is known for having a positive effect on muscle tension. The underblanket provides relaxing heat – whether for use after a long day sitting in your office chair or after exercising. After washing, bring the electric blanket to its original shape and preferably lay it flat on a clothes horse. In addition, the heated underblanket must not be wrung out, tumble dried, mangled or ironed.Set your washing machine to a particularly gentle cycle at 30°C and use a mild laundry detergent. To ensure the heated underblanket has a long life, it should not be washed too often. Instead, remove small marks by hand.
