Machine washable electric blankets
All of them say washable. Only some say how. This ranks them on the specificity of the instruction, because a vague instruction is how blankets get ruined.
We earn a commission on some links here, at no extra cost to you. It does not change what we recommend or the order the picks appear in. How we are funded.
Every heated blanket we track is machine washable and they do not all mean the same thing by it. Sealy publishes the most specific instruction — slow agitation, low spin, and no dry cleaning, bleaching or wringing by name — which is why it leads this page. The universal rules are the same everywhere: detach the controller first, wash cool and gentle, and make sure it is completely dry before it is powered again.

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.
100 W x 8 h = 0.80 kWh, x $0.1834/kWh = $0.15 per night

Where it falls short
- One controller only, so the whole bed runs at one temperature

The only queen here whose maker prints a wattage on the listing, and it happens to also be the one with two controllers.
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.
220 W x 8 h = 1.76 kWh, x $0.1834/kWh = $0.32 per night

- ETL and FCC certified with an 8-hour default auto shut-off
- Preheat cycle steps itself down instead of holding full heat all night
Where it falls short
- 6 heat levels where Sunbeam and Sealy give 10 to 12
- No warranty term on the listing
- 220 W with both sides up is the highest published draw of any bed blanket here
Who this is forCouples with different thermostats, and anyone who wants to know what the thing actually draws before buying it.
Skip it ifSkip it if you sleep alone. You are paying for a second controller you will never plug in, and the single-control Westinghouse publishes a lower 100 W.

One of very few listings that names the specific standard it was tested to, UL 964, plus a published 86-122 F range.
Where the wattage comes fromNo wattage published. Homemate does name the specific test standard (UL 964, the standard for household electric heating pads and blankets) and a temperature range of 86-122 F, which is more specific than most.

- Publishes a temperature range, which most throws do not
- Publishes the heating wire diameter, 2.2 mm, which nothing else in our set does

- The listing states 8 hours in one bullet and 10 hours in another for the same auto shut-off
Who this is forSomeone who reads certifications and wants the standard named rather than implied.

Who this is forSomeone who wants the Sunbeam controller and a warranty term in writing before they buy.
Skip it ifSkip it if you share the bed and disagree about temperature. It is single control, and no number of heat settings fixes that.
How we ranked these
- How specific is the published instruction? A maker that names the cycle, the spin speed and the prohibitions has told you how to keep the blanket alive. A maker that says machine washable and stops has not.
- Does it publish a drying rule? This is where the makers genuinely disagree, and it is the step that kinks elements.
- Does the fabric weight suggest it will survive it? GSM is published by most brands and is the closest thing to a durability figure in this category.
- Not ranked on how well any of them actually washes. We have not put one in a machine and we are not going to imply otherwise.
We have not handled these products and we do not claim to have. The full method, including the rubric weights and what we refuse to claim, is on our methodology page.
Washable is not a specification
Machine washable appears on every listing in this category. So does soft, so does auto shut-off, so does ETL certified. Claims that every product makes cannot help you choose between them, which is why this page ranks on the thing that actually varies: how much the maker is willing to tell you about the wash.
| Brand | Instruction as published |
|---|---|
| Sealy | No dry cleaning, no bleach, no wringing; low spin wash |
| Biddeford | Dryer safe; tumble dry on a low heat setting |
| Westinghouse | Tumble dry on low or line dry |
| Bedsure | Machine washable with the controller detached |
| Homemate | Machine washable; unplug the controller first |
Quoted from each maker's own listing, checked 2026-08-31 and re-verified 2026-09-13. Where the instructions that came with your blanket differ from this table, follow yours — they are the authority for your model.
Read that table for what is missing rather than what is there. Two brands name a drying method. One names prohibitions. Two say washable and leave the rest to you. None of them publishes a water temperature in degrees.
The one rule that destroys blankets
Detach the controller before the blanket goes anywhere near water. The controller is a sealed electronic module and the manual for every product in this category says it is not waterproof and must not be immersed. Wash it and it is finished, and unlike the element it fails in a way you notice immediately.
It is also the failure with the worst consequences, because a controller from another blanket is not a safe substitute: certification covers the controller and element as a matched pair. A washed controller usually means a replaced blanket. The full reason is on electric blanket controllers.
The drying disagreement, which is real
This is the one place the makers do not line up. Biddeford says dryer safe on low. Westinghouse says tumble dry on low or line dry. Sealy prohibits wringing and specifies a low spin but does not endorse a dryer at all.
The pattern that is consistent across all of them is a short low-heat tumble to knock most of the water out, then finish flat or on a line. Nobody in our set endorses drying a heated blanket to completion on high heat, because heat plus tumbling plus a wire mesh is the combination most likely to kink an element. Full sequence on how to wash a heated blanket.
Fabric weight is the closest thing to a durability number
No maker publishes a wash-cycle rating, so there is no published figure for how many washes a blanket survives. What most of them do publish is GSM, the fabric weight, and it is at least a real number.
- 290 GSM flannel / 200 GSM sherpa — Bedsure king, the heaviest face in our set.
- 280 GSM flannel / 200 GSM sherpa — Sealy throw.
- 240 GSM flannel / 200 GSM sherpa — Bedsure GentleSoft queen.
- 220 GSM flannel / 200 GSM sherpa — Bedsure full and throw. Homemate publishes 220 GSM double-sided flannel.
- 200 GSM double-layer flannel — Westinghouse queen and Sealy queen, the lightest published faces here.
We are not going to claim that a heavier face survives more washes, because nobody has published data that would support it. What GSM does tell you is what you are buying in fabric terms, and it is one of the few numbers in this category that is comparable across brands.
How often, which is the uncomfortable part
Less often than sheets. This is the genuine tension in the category: washability is the headline feature on every listing, and washing is one of the two things that shortens a heated blanket's life. The other is folding it hard for storage.
A top sheet between you and the blanket removes most of the reason to wash it, and costs nothing. If your blanket needs washing monthly, the cheaper fix is a sheet. When it does come off for the summer, roll it rather than folding it — a crease is a stress point in the wire. That is on storing a heated blanket.
Where each pick is the wrong buy
- Sealy queen dual — the clearest wash instructions here and no published wattage, so you cannot cost it.
- Westinghouse flannel queen — publishes 100 W and a drying rule, but ships one controller for the whole bed.
- Bedsure GentleSoft queen — publishes its wattage and its preheat curve; its wash instruction is the bare minimum.
- Homemate throw — a sofa throw, not a bed blanket, and no wattage published.
- Bedsure mattress pad queen — the pad is the format least likely to need washing, since a fitted sheet goes over it.
- Sunbeam Royal Posh queen — the best controller here and Sunbeam publishes neither a wattage nor a detailed wash instruction.
Questions people actually ask
- Can you put an electric blanket in the washing machine?
- Yes, and every product we track states it. Detach the controller and power cord first, use a gentle or delicate cycle in cool to lukewarm water with a slow spin, and never wring it. The full sequence is on our washing page.
- Which electric blanket has the clearest washing instructions?
- Sealy. Its listing names the prohibitions explicitly — no dry cleaning, no bleaching, no wringing — and specifies a low spin. Most makers say machine washable and stop there.
- Can you tumble dry a heated blanket?
- The makers disagree, which is worth knowing. Biddeford states dryer safe on low. Westinghouse states tumble dry on low or line dry. Sealy prohibits wringing and specifies low spin without endorsing a dryer. What none of them endorses is drying to completion on high heat.
- How often should you wash an electric blanket?
- Less often than sheets. Washing is one of the two things that shortens a heated blanket's life, the other being hard folding. A top sheet between you and the blanket removes most of the reason to wash it.
- What happens if you wash the controller?
- It is usually destroyed. The controller is a sealed electronic module and every manual states it is not waterproof. The blanket itself is often undamaged, which makes it worse: a controller from another blanket is not a safe substitute, because certification covers the controller and element as a matched pair.
