Electric blankets, from twin to king

What actually separates one from another

Almost every listing in this category says the same four things: it is soft, it is machine washable, it has an auto shut-off, and it is ETL certified. Those are table stakes. Every blanket on this page does all four. So they cannot be the reason to choose one.

Four things genuinely differ, and three of them are checkable before you buy:

• Whether the maker publishes a wattage. Three of ten do. Without it there is no way to compute what the blanket costs to run, and no way to compare it against a space heater or a heated mattress pad. See the watts, by model.
• One controller or two. A queen with a single controller heats the whole bed to one temperature. If two people sleep in it and one of them runs hot, that is the decision, and no amount of heat settings fixes it.
• How many heat steps and how long the timer runs. Sunbeam gives twelve steps and a 12-hour ceiling. Bedsure gives six steps and eight hours. Neither is wrong; they are different products.
• The warranty term, where one is stated at all. Biddeford and Sealy publish five years. Most of the rest publish nothing, which is itself information.

Sizes, and the one that surprises people

The obvious assumption is that a bigger blanket draws more power. It mostly holds, but not reliably. Bedsure's full-size blanket publishes 130 W on a single controller. Its queen publishes dual 110 W controllers, which is 110 W if only one side is running. So the smaller blanket can draw more than half the bigger one, and if you sleep alone on a queen it draws less than the full.

That is not a mistake in the specs. It is a reminder that wattage tracks the length and density of the heating element and the way the controller is configured, not the surface area of the fabric. It is also exactly why an averaged category figure of the kind other sites publish is worthless: the spread within a single brand is wider than the spread between sizes.

Blanket, throw, or mattress pad?

These are three different products and people buy the wrong one regularly. A blanket sits over you and heats the air around your body. A heated throw is a smaller version for a sofa, typically 50 by 60 inches, and it is a personal item rather than a bed one. A heated mattress pad goes under the fitted sheet and heats upward, which is a genuinely different sensation and, in our reading of the published specs, the option most people who complain about a blanket feeling heavy actually wanted.

If you are choosing between the first and the third, we wrote the comparison out in full: heated blanket versus heated mattress pad.

Before you buy: the three things worth checking

1. 1Where is the outlet? Biddeford prohibits extension cords and power strips outright. Sealy publishes a 19-foot total cord run. If your only socket is across the room, that decides the purchase before anything else does.
2. 2Can you wash it, and how? All of them say yes, and all of them mean something slightly different by it. The rules that actually break blankets are in washing an electric blanket.
3. 3Should the person using it be using one at all? There are real answers here for pacemakers, pregnancy, small children, people with reduced sensation, and pets. They are on who should not use one.
