A fitted underblanket is a different purchase from a heated throw
An electric blanket that goes under the sheet is not a heated throw with a skirt sewn on. It lives under your body weight for a third of the day, it gets pulled tight over a mattress corner every time the bed is made, and the controller dangles off the edge of the base where it gets kicked, stood on and yanked by the cord. That is a harder life than any throw gets on a couch. The design choices that matter are the ones that survive it, and most are invisible in the product photo.
I have spent 16 years in Erina fixing things that were sold on the glossy spec and failed on the boring one. Electric blankets are a clean example. The listing shouts about heat levels. What decides whether it is still working in four winters is how the wire enters the blanket, how the controller plug is strain-relieved, and whether the overheat circuit is a real sensing loop or a marketing line. None of that is on the box.
If you only want warmth on the couch, a 120W heated throw is the better tool and I cover those separately in the heated throws guide. A fitted underblanket is for the bed, and the five here are all fitted, all washable, and all claim overheat protection on the listing. Prices run from $46 to $139 at time of writing. The difference is mostly controller sophistication and the Sleep Perfect system on the two Sunbeams, not the heating wire, which does the same job in all of them.
The controller and the cord entry: where electric blankets actually fail
Open up a dead electric blanket and the heating wire itself is almost never the culprit on a blanket that has been used flat. The wire is a resistive element run in loops through channels in the fabric, and it is surprisingly tough. Three other things fail first. The controller, which has a small switching circuit, a triac or relay, and sometimes a microcontroller reading a thermistor line. The plug where the controller cord meets the blanket, which takes every tug. And the cord itself at the strain relief, where copper strands fatigue from being bent the same way every night for years.
A controller failure usually looks like this: the blanket stops heating, or heats on one setting only, or the LED flashes an error and refuses to start. Inside, the common faults are a cracked solder joint where the cord enters the board (mechanical, from cord movement), a failed triac (electrical, from switching a resistive load thousands of times) or a controller that has detected an open circuit in its sensing wire and locked out on purpose. That last one is the safety system doing its job. It is also the one nobody can fix at home, because the sensing wire runs the length of the blanket.
Cord entry failures are slower. The outer sheath cracks first, then the insulation underneath, then a strand breaks and the blanket becomes intermittent. Flex it and it works. Let it settle and it dies. By the time you notice, you have a conductor carrying mains current through a fraction of its original copper, and that is where heat builds. The fix is not tape. If a controller cord is cracked, cut or feels hot near the plug, the blanket is done unless the maker sells a replacement controller as a part. Detachable controllers, which the LINENOVA listing states and the Sunbeam dual-control setup implies, at least make that replacement possible. A moulded-in controller means the whole blanket goes.
We see the same mechanical story on laptop chargers every week at our Central Coast repair bench. Same copper, same bend radius, same failure. The lesson travels. Route the cord so it does not bend sharply over the mattress edge, and never wrap it around the controller for storage.
Overheat protection and auto-off: the two specs that matter
Every blanket here says overheat protection on its listing. The phrase covers two quite different implementations, and listings rarely say which. The simple version is one or more thermal cut-outs in the wire loop that open when a local spot gets too hot. Simpler to build, slow to react, and if the cut-out is a one-shot thermal fuse the blanket is dead for good once it trips. The better version is a sensing conductor running alongside the heating wire for its full length. The controller monitors that conductor continuously and switches off if any point along the blanket exceeds the threshold, or if the current draw looks wrong. The Sunbeam listings describe exactly that: switches off if abnormal heat or current is detected. Costway adds short-circuit protection, the current half of the same idea. The others say overheat protection and leave it there.
Why it matters: a bunched fold traps heat in a small area. A blanket with full-length sensing notices and cuts out. A blanket with a couple of point cut-outs notices only if the hot spot happens to be near one. Neither is a licence to run it folded, but one of them fails safer.
Auto-off is the other spec I would not buy without. It is not about electricity, it is about the blanket being on at 3am with the room cold, the controller cooking at full duty cycle and nobody awake to notice a fault. Four of the five state it, with different windows. Sunbeam gives 1, 3 or 9 hours. Costway gives 9 hours per side. LINENOVA gives 3 hours. Dreamaker's listing does not state an auto-off figure, so I am not assuming one. If a listing says nothing about auto-off, assume it runs until you turn it off, and treat that as a reason to pick something else for a bed where someone falls asleep with it on.
Dual control and heat zones: not just a comfort feature
On a double or larger bed, dual control means two independent heating circuits and two controllers, one per side. The obvious benefit is that one person runs it on 2 and the other on 6. The less obvious one is longevity. If one side is switched off most nights, that side's controller and wire see half the thermal cycling of the other, and when one controller dies the other side still works while you sort out a replacement. On the single-controller Sunbeam King Single, which is a bed for one, none of that applies and the simpler design is the right call.
Check the listing wording, because dual control is size-dependent. Dreamaker says individual heat zones and controllers for double and above. LINENOVA says dual controllers on double, queen and king. Costway's queen listing says dual controllers with 9 heat levels and a 9-hour timer per side. The Sunbeam Queen states dual controls with 6 heat levels. If you order the single size of any of these you get one controller, which is fine, but do not expect two.
One physical note on dual control: two cords, two plugs, two controllers dangling off the bed base. That doubles the cord-entry exposure I described above. Run both cords down the same side if the bed allows, keep them off the floor where the vacuum will find them, and plug them into the wall or a powerboard that has nothing else heating on it. An electric blanket draws little, but I still would not share a board with a fan heater, and the 2,400W ceiling on a standard 10A socket is easier to hit than people think.
What the SAA and RCM marks mean, and what they do not
Three of the five listings lean on Australian safety certification in their text. Dreamaker says tested to Australian SAA safety standards. Costway says tested to Australian SAA standards. LINENOVA says SAA-certified. The Sunbeam listings do not use the phrase, which is not a mark against them (Sunbeam is an Australian brand selling through normal retail and the product carries the compliance marking you would expect), it just means I cannot quote it from the listing.
Here is what the mark actually tells you. An electric blanket sold legally in Australia is a declared (level 3) electrical article, which means it must be certified to the relevant standard and carry the RCM, the Regulatory Compliance Mark, the tick inside a triangle. SAA is the older approval body name that listings still use loosely. When a seller says SAA-certified, the useful part of that claim is that a certificate exists and the product was tested to AS/NZS 60335.2.17, the appliance standard for blankets, pads and flexible heating appliances. That standard is where the requirements for the overheat cut-out, the cord anchorage and the flexing test live. The mark is a claim that those tests were passed on a sample.
What it does not tell you is anything about controller build quality beyond the minimum, how the blanket survives washing, or whether the overheat system is full-length sensing or point cut-outs. Both pass. The mark is the floor. I want it on the physical product: look for the RCM on the controller moulding or the label when it arrives, and if it is not there, send it back.
Never folded: deep skirts, elastic bands and why fit is a safety spec
The rule on every electric blanket label is never use it folded or rucked, and it is there because of the physics in the overheat section. The wire is designed to shed heat evenly into the mattress below and the sheet above. Fold it and two heated layers face each other with nowhere for the heat to go. That is how a blanket that runs at a perfectly safe surface temperature when flat can scorch when bunched. Fitted designs exist to make flat the default, and the fit details on the listing are therefore safety details, not just convenience.
Skirt depth is the first one. Dreamaker states a 50cm deep fitted skirt. LINENOVA states 40cm. On a modern pillow-top mattress that can be 35cm thick, a shallow skirt pops off the corner in the night and the blanket rides up and creases under your hip. Costway and LINENOVA both add elastic fixing bands as well, which hold the panel flat even if the skirt shifts. The Sunbeams say fully fitted and leave depth unstated, so measure your mattress and check the current listing before ordering those.
Fabric weight plays into flatness too. Costway and LINENOVA state 450gsm non-woven fabric and the Sunbeams state 250gsm. A heavier panel drapes flatter. It also holds more water after a wash and dries slower. Storage is the other folding trap. Roll the blanket around a cardboard tube over summer rather than folding it into a cupboard, because a hard crease left in the wire for eight months is a stress point that shows up as a hot spot or a break the following winter.
Washing without killing the wire
All five are listed as machine washable, and this is where blankets get killed early. The wire survives water fine. What it does not survive is being wrung, being spun hard with a hard kink in it, or being put back on the bed and switched on while the channels are still damp. Costway's listing gives the most specific instruction, gentle cycle at 30 °C, and I would apply that to all of them regardless of what the care label allows.
The procedure I follow: unplug the controllers first (detachable ones come off; moulded ones you bag and keep out of the drum). Wash on the gentlest setting the machine has, cold or 30 °C, short spin or no spin. Do not use the dryer unless the label explicitly permits it. Dry flat or draped over two lines so the weight is spread, never pegged by one corner with the wire hanging. Before plugging back in, run your hands along every channel. If any section feels damp, wait. Moisture in the connector is the failure that shows up weeks later as corrosion and an intermittent fault, the same story I wrote up in our water damage explainer for phones and laptops.
Last check before the first use after washing: lay it flat on the bed, switch on the highest setting for five minutes, then run a hand over it feeling for a cold stretch (a broken run) or an unusually hot spot (a kinked one). Either means it goes in the bin, not back under the sheet.
Running cost: pre-heat, then off
None of these listings states a wattage, so I will not invent one. Fitted blankets in this class typically draw in the tens of watts per side on low and somewhere near 100W to 150W flat out, but treat that as background, not a spec for any listed product. The useful number is the tariff. At the AU average of roughly 33c per kWh, a device drawing 100W costs about 3.3c per hour. Even an hour on high before bed and a couple of hours on low is a few cents a night. A 2,000W fan heater running the bedroom costs about 66c per hour flat out at the same tariff. The blanket heats you, not the room.
The trick that makes it nearly free is pre-heat then off. Put it on high 20 to 30 minutes before bed (the Sunbeams claim the bed is warm in 5 minutes, which matches what I have measured on similar systems), get in, then switch it off or drop it to the lowest setting with the auto-off armed. A doona holds the heat you just put into the mattress for hours. The Sleep Perfect system on the Sunbeams does a version of this automatically by adjusting output to body and room temperature changes, and it is the main thing the extra money buys.
If you want the real figure for your blanket rather than my assumption, a plug-in meter will give it to you in one night, and I cover the ones worth owning in the smart energy monitors guide. A blanket is also one of the few heating loads small enough to run from a battery in a blackout.

Sunbeam Sleep Perfect Queen Fitted Electric Blanket, Dual Control (BLA6351)
ASIN B0BXHS4VP3 • $139.00 • Ships from Amazon AU
This is the one I would put on my own bed, and the reason is the overheat description on the listing. Sunbeam says it switches off if abnormal heat or current is detected, which is the language of a full-length sensing system with a controller watching it, not a couple of thermal cut-outs in the wire. Add dual controls, six heat levels per side and an auto-off you can set to 1, 3 or 9 hours and you have every protective feature I asked for in the sections above, in a fully fitted queen, for $139 at time of writing. It sits at #7 in Amazon AU's Blankets, Throws and Patchwork Quilts category, which is a broad category full of ordinary bedding, so that rank means something.
The Sleep Perfect system is the functional difference from the rest of the list. The listing says it warms the bed in 5 minutes and then maintains your setting by adjusting heat to body and room temperature changes. In practice that is a controller reading its sensing loop and backing off as the mattress and you warm up, rather than a dumb on-off at a fixed duty cycle. It means less thermal cycling in the wire over a night, and it means you can leave it on a low setting without the bed slowly climbing. Sunbeam also describes an antibacterial fabric treatment intended to inhibit bacteria and mould growth on the fabric, a 250gsm non-woven polyester top layer and what it calls exclusive Italian wire technology. I cannot verify the wire claim from a listing, but the fabric weight is stated and is lighter than the two entry picks.
It is washable per the listing, and with two controllers it is the pick where detaching them before the wash matters most. Sunbeam is an Australian brand with a normal retail presence, which is relevant when you need a replacement controller in year four: there is somewhere to ask. That, plus the sensing-based overheat system, is what the extra $60 to $90 over the entry picks is buying. It is not buying a deeper skirt or a heavier panel, and on a slippery mattress protector I would still add a fitted sheet pulled tight over the top to keep it flat. Treat the wash the same way as any other: controllers off, gentle cycle, dry completely before it goes back on.
Honest caveats: Honest caveats: the listing does not state skirt depth, wattage or whether the controllers are detachable, so check the current listing on all three before ordering. The 250gsm panel is lighter than the two 450gsm entry picks and may bunch more easily on a slippery mattress protector. The antibacterial treatment is a fabric claim; it does nothing for the electrics.
Best for: A couple on a queen who want a set-and-forget blanket with the most clearly described overheat system on the list.

Sunbeam Sleep Perfect King Single Fitted Electric Blanket (BLA6331)
ASIN B0BXHQD6N5 • $102.00 • Ships from Amazon AU
Same system as the queen above, sized for one. The listing describes the same Sleep Perfect temperature-holding behaviour, the same six heat levels, the same 1, 3 or 9 hour auto-off and the same overheat protection, in a fully fitted king single at $102 at time of writing. It shares the #7 rank in Amazon AU's Blankets, Throws and Patchwork Quilts category with the queen because Amazon groups the sizes under one listing family. One controller rather than two, which on a bed for one is not a compromise. It is one fewer cord to route, one fewer plug to fail, and one fewer controller to find a home for down the side of the bed.
The king single is the size I would point at for a teenager's room or a spare bed, and that is exactly where auto-off earns its keep. A blanket in a kid's room gets switched on and forgotten. The 1-hour setting means it warms the bed and then shuts itself off before anyone is asleep on it, which is how I would configure it. The Sleep Perfect system's habit of backing off as the bed warms is also useful on a narrower mattress, where a fixed duty cycle would overshoot faster because there is less thermal mass to heat. Six heat levels on a single bed is more resolution than most people will use, but the low end of that range is where a held setting overnight should sit.
The caveat shared with its bigger sibling is that Sunbeam's listing is light on physical detail. Fabric is 250gsm non-woven per the listing; skirt depth, wattage and controller detachability are not stated. It is washable. For the money, it is the only single-bed pick here with the descriptive overheat language I rate, and that is what justifies it over the $46 and $60 options in a smaller size. If the price gap bothers you, the honest comparison is the LINENOVA in a single, which gives up the Sleep Perfect system but keeps detachable controllers and a 3-hour auto-off.
Honest caveats: Honest caveats: the listing does not state skirt depth or wattage, and the single controller is the only one you get, so if it fails the blanket is off until a replacement is sourced. At $102 it is more than double the price of the Costway in a smaller size; you are paying for the Sleep Perfect system and the brand, not extra coverage.
Best for: A single sleeper, a teenager's bed or a spare room where auto-off and a clearly described overheat cut-out matter more than price.
Size listed: King single, fully fitted • Controls: Single controller, 6 heat levels • Auto-off: 1, 3 or 9 hours • Safety: Overheat protection (listing) • Fabric: 250gsm non-woven, antibacterial treatment • Heating: Sleep Perfect temperature-holding system • Washable: Yes (listing) • Price: $102 at time of writing • Rank: #7 in Blankets, Throws & Patchwork Quilts (Amazon AU)

Dreamaker Dual Control Fitted Electric Blanket, Queen
ASIN B07TQT48YC • $79.95 • Sold by Time2Shopau on Amazon AU
The Dreamaker is the fit pick. A 50cm deep fitted skirt is the deepest stated on this list by a margin, and on a thick pillow-top mattress that is the difference between a blanket that stays flat and one that creeps. It is sold by Time2Shopau on Amazon AU at $79.95 at time of writing and sits at #2 in the Blankets, Throws and Patchwork Quilts category, which is the same broad category the Sunbeams rank #7 in, so it is outselling them there. The listing states individual heat zones and controllers for double and above, three heat settings, a low-glare LED controller, overheat protection and testing to Australian SAA safety standards. Machine washable, with sizes from single to super king.
Three heat settings is fewer than anything else here, and I am fine with that. Most people use two: high to pre-heat, low to hold. The low-glare LED is a small thing that matters in a dark bedroom, because a controller that lights up the wall is a controller that gets shoved under the bed, cord and all, which is how cords get crushed. The dual zones on the queen mean each side is its own circuit, which is the longevity argument I made earlier. The SAA wording on the listing is the seller's claim; check for the RCM on the controller when it arrives, and keep the packaging until you have done so.
What the listing does not say is just as important. There is no auto-off stated, no fabric weight and no wattage. Of the five, this is the one I would most want to see an auto-off figure for before buying for a bed where someone falls asleep with it on. If the current listing has added one by the time you read this, it moves up. If not, treat it as a blanket you switch off yourself, which for a couple who pre-heat and then turn it off before sleep is a non-issue, and for a kid's room is a reason to look at the Sunbeam King Single instead.
Honest caveats: Honest caveats: no auto-off is stated on the listing, which is the biggest gap on this list and the reason it is not my overall pick. Fabric weight, wattage and controller detachability are also not stated. It is a marketplace seller listing, so confirm the RCM marking on the physical product and keep the order record for warranty.
Best for: A queen or larger with a thick mattress where skirt depth matters most, for someone who will switch the blanket off themselves.
Size listed: Queen (single to super king available) • Controls: Dual zones and controllers on double and above, 3 heat settings • Controller: Low-glare LED • Auto-off: Not stated on the listing • Safety: Overheat protection; tested to Australian SAA standards (listing) • Skirt: 50cm deep fitted skirt • Washable: Machine washable • Price: $79.95 at time of writing • Rank: #2 in Blankets, Throws & Patchwork Quilts (Amazon AU)

LINENOVA Premium Fitted Electric Blanket, King, 40cm Skirt, Dual Control
ASIN B0F29MZDDD • $60.44 • Sold by NOVOBAY on Amazon AU
At $60.44 at time of writing for a king, sold by NOVOBAY on Amazon AU, this is the most blanket per dollar on the list and it is #1 in Amazon AU's Electric Mattress Pads category, which is the narrow category that actually describes these products. The listing states SAA certification, an overheat protection system, dual controllers on double, queen and king, three heat settings and a 3-hour auto-off. Physically it has a 40cm deep skirt, elastic bands, 450gsm non-woven fabric, detachable controllers and Braille markings on the controllers. It is machine washable. That is a longer list of stated physical detail than either Sunbeam listing offers, which counts for something when the listing is all you have.
Two details here are the ones I care about. Detachable controllers mean the part that fails most often can, at least in principle, be replaced without binning the blanket, and it means you can wash the panel without bagging a live controller in the drum. The 450gsm panel with elastic bands is heavier and flatter than the 250gsm Sunbeams, which helps the never-folded rule on a slippery mattress protector. The 3-hour auto-off is a single fixed window rather than a choice, which suits pre-heat-then-forget well: it is long enough to warm the bed and hold it through falling asleep, short enough that it is off by the small hours. The Braille markings are a real accessibility feature and also mean you can find the setting by feel in the dark without lighting the controller.
The gaps are wattage and any description of how the overheat system works beyond the phrase. Three heat settings and a 3-hour timer are simple, and simple controllers have fewer things to crack. For a king bed, at this price, with detachable controllers and a stated auto-off, this is the one I would hand to someone who asked for the value pick without a sermon attached. The usual marketplace-seller caution applies: confirm the RCM mark on the controller when it arrives, keep the order record, and do the flat-on-the-bed five-minute test before the first night.
Honest caveats: Honest caveats: the listing does not state wattage or describe the overheat mechanism, and 3 hours is the only auto-off window available. It is a marketplace seller, so check for the RCM marking on the controller on arrival. A 40cm skirt is good but 10cm shallower than the Dreamaker, so measure a very thick mattress first.
Best for: A king or queen bed on a value budget where detachable controllers and a stated auto-off are the priorities.
Size listed: King, fully fitted • Controls: Dual detachable controllers on double/queen/king, 3 heat settings, Braille markings • Auto-off: 3 hours • Safety: SAA-certified; overheat protection system (listing) • Skirt: 40cm deep skirt with elastic bands • Fabric: 450gsm non-woven • Washable: Machine washable • Price: $60.44 at time of writing • Rank: #1 in Electric Mattress Pads (Amazon AU)

Costway Queen Dual Control Fitted Electric Blanket, 9 Heat Settings
ASIN B0F7XRGLCZ • $45.95 • Sold by COSTWAY-AU on Amazon AU
The Costway is $45.95 at time of writing for a queen, sold by COSTWAY-AU on Amazon AU, and #2 in the Electric Mattress Pads category behind the LINENOVA. For that money the listing states dual controllers, nine heat levels and a 9-hour timer per side, elastic fixing straps, 450gsm non-woven fabric, testing to Australian SAA standards, and overheat plus short-circuit protection. It is machine washable on a gentle cycle at 30 °C, which is the only listing here that gives a specific wash instruction, and it is the one I would follow for all five. Sizes run single to king, and the queen is the dual-control size.
Nine heat levels is more than anyone needs and that is not a criticism, it just means the steps between settings are small. The 9-hour timer per side is the longest window on the list, which cuts both ways. It will outlast any pre-heat you can imagine, and if someone sets it and falls asleep the blanket runs most of the night before it cuts out. I would use it on a low setting if it is staying on. The short-circuit protection wording is the current-sensing half of a proper overheat system and I take it as a small positive sign about the controller, though the listing does not describe the heat-sensing side beyond the phrase.
The elastic fixing straps and the 450gsm panel are the same flatness argument as the LINENOVA. What is not stated is skirt depth, wattage or controller detachability. At $46 for a dual-control queen with a stated timer and washing instructions, it is a sensible first electric blanket, and the one to put on the spare bed. Measure the mattress depth before ordering, check the RCM on the controllers when it arrives, and run the five-minute flat test before anyone sleeps on it. Do that and the price stops being the interesting part.
Honest caveats: Honest caveats: skirt depth is not stated, so fit on a thick mattress is unknown until it arrives. Wattage and controller detachability are not stated either. The 9-hour timer is the only window, so it is not a short pre-heat-then-off setting; you turn it off yourself for that. Marketplace seller, so verify the RCM mark on arrival.
Best for: A spare bed or a first electric blanket on a queen where dual control and a stated timer matter and the mattress is a standard depth.
Size listed: Queen, fully fitted (single to king available) • Controls: Dual controllers, 9 heat levels per side • Auto-off: 9-hour timer per side • Safety: Overheat and short-circuit protection; tested to Australian SAA standards (listing) • Fit: Elastic fixing straps • Fabric: 450gsm non-woven • Washable: Machine washable, gentle cycle, 30 °C • Price: $45.95 at time of writing • Rank: #2 in Electric Mattress Pads (Amazon AU)

What we see fail at the bench: electric blankets
An electric blanket that comes through the door is usually a few winters old and has one of three complaints: it does nothing, it works on one setting or one side, or it only works when the cord is held at a certain angle. The blanket panel itself is rarely the problem on one that has been used flat. The controller, the cord and the plug between them carry almost all the failures, and most of them are mechanical before they are electrical.
Cracked solder at the controller cord entry
The controller cord is soldered to a small board inside the moulding and the strain relief is a rubber boot. Years of the cord being pulled as the bed is made, or bent over the base as the controller dangles, flex the board at the joint. A hairline crack forms, the joint goes high-resistance, and you get a blanket that works when the cord is wiggled. Sometimes that joint also gets warm, which softens the plastic around it. If a controller is discoloured or smells hot near the cord, stop using it. A detachable controller can be swapped; a moulded one retires the blanket.
Triac or relay failure inside the controller
The controller switches a resistive load on and off thousands of times a night to hold a setting. The switching part, usually a triac on the better units or a small relay, eventually fails. A failed-open triac means no heat on any setting and a dead-looking blanket. A failed-short one means full heat regardless of setting, which the overheat system should catch if it is the full-length sensing type. That is the scenario that separates real overheat protection from the phrase. It is also why I will not buy a blanket without auto-off: a stuck controller at 3am with nobody awake is the case the timer exists for.
Corrosion and open circuits after washing
A blanket washed, spun hard and put back damp comes to me two or three weeks later with an intermittent fault. Water in the plug between controller and blanket sits on the pins, the copper turns green, and the contact resistance climbs until the controller either locks out or the connection cooks. Spinning with a kink in the panel can also break a wire run, which shows up as a cold stretch. Neither is repairable in any sensible way. Gentle cycle, no hard spin, dry flat and completely, and run your hand along the channels before the first use. It is the one failure here that is entirely in the owner's hands.
Decision tree: which one should you actually buy?
- Couple on a queen, want to set it once and stop thinking about it? → The Sunbeam Sleep Perfect Queen (BLA6351) at $139. Dual control, 1/3/9 hour auto-off and the clearest overheat description on the list.
- One person, a teenager's room or the spare bed, single size? → The Sunbeam Sleep Perfect King Single (BLA6331) at $102. Same system, one controller, set the 1-hour auto-off and forget it.
- Thick pillow-top mattress and every other blanket has crept off the corners? → The Dreamaker Dual Control Queen at $79.95 with its 50cm skirt, on the understanding that no auto-off is stated and you switch it off yourself.
- King bed, want detachable controllers and a stated auto-off without spending more than about $60? → The LINENOVA Premium King at $60.44. 40cm skirt, elastic bands, 450gsm panel, 3-hour auto-off, Braille controllers.
- First electric blanket, spare bed, standard mattress, dual control for under $50? → The Costway Queen at $45.95. Nine levels and a 9-hour timer per side, with the only explicit wash instruction on the list.
- Already own one and it only works when you wiggle the cord, or the controller smells hot? → Stop using it tonight. Bring the blanket and both controllers to our Erina workshop and we will tell you honestly whether the controller is replaceable or the blanket is done.
Frequently asked questions
Is it safe to leave an electric blanket on all night?
The safest pattern is pre-heat then off: run it on high for 20 to 30 minutes before bed, then switch off or drop to the lowest setting with the auto-off armed. If you do leave it on, use a blanket with a stated auto-off and an overheat system (all five picks here claim overheat protection; four state an auto-off window), keep it flat and never folded, and check the controller and cord for heat or cracking at the start of each winter. Anything that works only when the cord is held a certain way is retired, not tolerated.
What does SAA or RCM mean on an electric blanket listing?
Electric blankets are declared electrical articles in Australia, so a legally sold one has been certified to the appliance standard (AS/NZS 60335.2.17) and carries the RCM, the tick-in-a-triangle Regulatory Compliance Mark. SAA is the older approvals name that listings still use loosely. The mark tells you a sample passed the standard's tests, including the overheat cut-out and cord flexing tests. It does not tell you how good the controller is beyond that minimum. Look for the physical mark on the controller or label when the blanket arrives, and return it if it is missing.
How much does an electric blanket cost to run in Australia?
None of the five listings states a wattage, so the honest answer is measure it with a plug-in meter. The arithmetic is simple once you have the number: at the AU average tariff of roughly 33c per kWh, a device drawing 100W costs about 3.3c per hour. An hour on high to pre-heat and a couple of hours on low is a few cents a night. A 2,000W fan heater running all night costs about 66c per hour flat out at the same tariff, which is why heating the bed beats heating the room.
Can I machine wash a fitted electric blanket?
All five here are listed as machine washable. Detach the controllers first where the design allows (LINENOVA states detachable controllers; the others do not say). Use the gentlest cycle, 30 °C or cold, and a short or no spin. Costway's listing specifies gentle at 30 °C and I would apply that across the board. Dry flat or across two lines, never by one corner, and do not use it until every channel is completely dry. Most wash-related failures are moisture in the connector or a wire broken by a hard spin with a kink in the panel.
Why does my electric blanket only work when I move the cord?
That is almost always a cracked solder joint where the cord enters the controller board, or a broken strand inside the cord at the strain relief. Both are mechanical failures from years of the cord bending over the bed base. The connection is intermittent and high-resistance, and high-resistance joints carrying current get warm. Stop using it. If the controller is detachable, a replacement from the maker fixes it; if the controller is moulded to the cord, the blanket is finished. Do not tape the cord and keep going.
Is dual control worth it on a queen or king?
For two people, yes, and not only for comfort. Each side is its own circuit with its own controller, so one side can run at a lower setting or stay off, which halves the thermal cycling on that side's wire and controller. If one controller fails the other side still works while you sort out a replacement. Dreamaker, LINENOVA and Costway all state dual controllers on double and above; the Sunbeam Queen states dual controls. On a single or king single you get one controller, which is the right design for one sleeper.

Electric blanket only works when you wiggle the cord?
That is a cracked joint at the controller or a fatigued cord, and it is the kind of fault that gets warm before it gets worse. Unplug it and bring the blanket and controllers in to our Erina workshop. After 16 years of board-level work on the Central Coast we will tell you straight whether the controller can be replaced or the blanket has done its time.
