100 W stated on the listing, 10 heat levels and a 12-hour timer. The cheapest bed blanket to run of anything here that publishes a number at all.

Where the wattage comes fromWestinghouse states it directly in the first listing bullet: "a 100W, 60Hz heating blanket". This is a single-controller queen, so 100 W is the whole blanket rather than one side of it.

What it does well

• +Machine washable on cold, gentle

Where it falls short

• -One controller only, so the whole bed runs at one temperature
• -No warranty term on the listing
• -Westinghouse's other queen listings do not publish a wattage, so the figure is model-specific

Who this is forA solo sleeper, or a couple who genuinely agree on temperature and want the lowest running cost on the page.

Skip it ifSkip it if you share a bed with someone who runs hot. There is one controller and no way to split the blanket.

Where the wattage comes fromBedsure's listing states the blanket runs on 120V AC at 60Hz with dual 110W controllers. Two controllers at 110W each is 220W with both sides at full, or 110W if only one side is on, which is how most couples actually use it.

The short answer, in a table

What the second controller actually costs to run

This is the part most comparisons get wrong, including some of ours if we were careless about it. A dual-control blanket's rated wattage is normally the sum of both controllers. Bedsure's queen is dual 110 W, which is 220 W with both sides at full and 110 W with one side running.

So the honest comparison is not 220 W against 100 W. It is this:

• Both of you using the heat. 220 W on the Bedsure, against 100 W for the whole Westinghouse. The dual-control blanket costs about double, and it is heating two zones to two temperatures, which is what you bought it for.
• One of you using the heat. 110 W on the Bedsure against 100 W on the Westinghouse. Almost identical. A couple where only one person wants heat pays roughly single-control money on a dual-control blanket.
• Sleeping alone on a dual-control blanket. Also 110 W, for a second zone you never switch on. You paid for a controller and a cable run you do not use, and you run 10 percent above the lowest published figure on the shelf.

Every rated wattage here is a ceiling rather than an average: a thermostatic blanket cycles its element off once the bed is warm. The arithmetic and its rate source are on what an electric blanket costs per night.

The case for dual control

There is one, and it is strong. Almost every complaint about a shared heated blanket resolves to the same sentence: one person is too hot. It is not a defect and no number of heat settings fixes it, because on a single-controller blanket every setting applies to the whole bed.

What happens in practice is that the blanket gets set to whatever the colder person can tolerate, which satisfies neither, and by February it is in a cupboard. A second controller costs more and adds a cable; it is also the difference between a blanket that stays on the bed and one that does not. The dual-control picks, with per-side wattage where it is published, are on dual control electric blankets.

The case for single control

Also strong, and much less often made, because nobody sells you a feature by leaving it out.

• Lower published draw. The Westinghouse queen's 100 W is the lowest figure any bed blanket in our registry stands behind, and it covers the whole 84 x 90 inches rather than half of it.
• One thing to detach before washing. The single most expensive mistake in this category is washing a blanket with the controller still attached. A dual-control blanket gives you two chances to make it, and forgetting the second is exactly as destructive as forgetting the first - see how to wash a heated blanket.
• One cable, one plug. Two controllers means two cords running to two sides of the bed and, on most models, two sockets. Sealy publishes a 19-foot total cord run on its dual-control queen, which tells you how much cable is involved.
• Simpler at the wall. If the only reachable outlet is on one side of the bed, a dual-control blanket is the harder product to install, not the easier one.
• Usually cheaper. Fewer electronics, lower price, in every pair we have compared at the same size.

Which sizes actually ship which

This is where orders go wrong, because several brands change the configuration by size under the same product name.

Two things fall out of that table. Westinghouse is the only brand in our set that ships a single controller at king size, which is also why it is the brand that publishes the lowest draw. And dual control essentially does not exist below full: nobody sells it at twin, and if they did you should not buy it, because one person at one temperature is the entire scenario a twin bed describes.

Four questions that settle it

1. 1Does anyone else sleep under it? No means single control, and the rest of these questions do not apply.
2. 2Do you and your partner actually disagree about temperature? Plenty of couples do not. If you both want the same setting, you are paying for independence you will not use.
3. 3Is there a reachable socket on both sides of the bed? Two controllers means two cords and usually two plugs. This decides more purchases than it should.
4. 4Would a [heated mattress pad](/heated-mattress-pads/dual-control) be the better format? It offers the same dual-zone idea under the fitted sheet, it cannot slide off, and one of them publishes its wattage.

If you sleep alone, what to actually buy

Three single-control blankets are worth knowing about, and they answer different questions.

• The running cost. Westinghouse flannel queen, 100 W published, ETL and FCC, 10 levels, a 1 to 12 hour timer, 200 GSM flannel. No warranty term stated.
• The controller. Sunbeam Royal Posh Velvet queen, 12 heat settings and a backlit display you can read at 3am, plus the one stated warranty in Sunbeam's blanket range - five years. No wattage and no certification mark named.
• A single bed. Sealy twin, 62 x 84 inches, 10 settings over a published 87 to 126 F, ETL and FCC, five years. The widest published temperature band of anything we track.

And one caution that applies to all three: a single-control blanket on a bed that later becomes a shared bed is not upgradable. The controller is matched to the element it was certified with and a second one cannot be added, for the reasons on electric blanket controllers.
