I’ve tested a huge variety of products in my never-ending quest to find the best heated electric blankets and throws that will help this beleaguered reptile stay warm. Dreamland certainly makes some of the best that I’ve tested, but where does the Snowed In Organic Cotton Warming mattress protector sit on the list?

I have no qualms in saying that this is one of the best electric blankets I’ve tested, beyond a couple of small drawbacks. I tested both a single size and a double with dual controllers – here’s what I thought about both. 

The Dreamland Snowed In Warming Mattress Protector is made with a 200 thread count organic cotton cover and a 100% polyester fibre filling, with a huge elastic skirt that will fit mattresses up to 38cm deep. There are six heat settings and three timer settings, plus overheat protection and auto shut off. Like the Dreamland Heated Duvet I’ve just tested, the protector is both machine washable and tumble dryer safe – although you will need to tumble dry it on a low setting and take it out while it’s still slightly damp to dry it flat. 

The protector comes in four sizes (single, double, king and super king) but, oddly, different variations are available from different retailers. At the time of writing (March 2026) the Dreamland site stocks the single size for £100, a double (with one controller) for £125 and a king size (with dual controllers) for £150. 

However, if you want a double with dual controllers (living with a hot sleeper, I know I do) or a super king, you’ll need to go to Argos. These are priced at £140 and £170 respectively. 

The Snowed In heated protector is slightly more expensive than Dreamland’s Hunker Down Scandi Sherpa electric blanket (£115) and the Beurer Indulgence Heated underblanket (£100), both of which are a double with dual controllers. Of these, the Hunker Down is a more traditional electric blanket with straps to attach it to the mattress, while the Beurer has a skirted design. Cheaper options are available, such as the Silentnight Comfort Control electric blanket at £35 (or, if you still want dual controllers, the Yours & Mine blanket at £40 for a double), but these often don’t cover the entire surface of the mattress. 

Dreamland’s heated protector comes with a three-year manufacturer’s guarantee (whether you buy it from Argos or directly from Dreamland), but you don’t get a sleep trial as you do with some other brands.  

When testing heated blankets and throws, I always run the same tests to see how they perform against each other. The Dreamland Snowed In Warming Mattress Protector performed excellently when it came to my temperature tests. 

After taping a temperature probe to the protector (positioned near one of the heating element wires), I recorded temperature increases over 10 minutes. After 10 minutes on full power (setting six), the protector had reached an impressive temperature of 54°C, which increased to 58°C when I repeated the test with a duvet on top. On half power (setting three), it reached 27.2°C after 10 minutes – a good result, but not quite as warm as the Beurer Indulgence (29.8°C).

After an hour of heating, I also tested temperatures on top of the protector with an infrared thermometer gun. Again, results were impressive, with temperatures reaching a maximum of 47°C towards the top. At the bottom left and right corners, results were a bit lower at 30.5°C and 29.8°C respectively (more on that later). Finally, I also ran power consumption tests to see how efficient the Indulgence is. On full power the blanket used 35W to heat up and an accumulated 0.020kWh after 30 minutes. On half power, these readings were 30W and 0.015kWh respectively. Pretty good results considering its max temperatures at full power. 

As for the all-important real-life testing, I absolutely loved sleeping on the Dreamland Snowed In Organic Cotton Warming Mattress Protector. Temperatures were impressive on full power, and it warmed up quickly – even if Dreamland’s claim of a five minute heat up is a little optimistic: I’d probably give it 10 minutes at least. As a lightweight person, I can often feel the wires in electric blankets, which can become a little uncomfortable. However, perhaps thanks to the thicker padding, I couldn’t feel any wires here at all. 

On top of all this, you can keep it on during the summer as a regular mattress protector, with cables detached, helping to protect your mattress from stains and spills. Be aware that it’s not waterproof but, as I explained above, it is conveniently machine washable. 

Sensibly, the Dreamland isn’t heated under the pillow area, and the organic cotton cover means that the protector is really breathable – something my hot sleeping husband appreciated as he kept his side of the protector firmly switched off!

I did have a couple of issues with the Dreamland, the main one being the brand’s inexplicable choice not to extend its wiring all the way to the bottom of the protector’s surface. I found that, as a tall person, this did no favours when it came to keeping my feet warm – which was very annoying.

I also didn’t like the placement of the connectors for the controller, feeling they were too low down (they’d be better hidden underneath the pillow), and the raised surface of the connector feels a little uncomfortable if you roll onto it by accident.  

This is a fantastic electric blanket: it’s comfortable to sleep on, produces impressive heat and I loved the fact that it can double as a regular mattress protector in the summer. 

There’s no getting away from the fact that it’s a pricier option, and I was annoyed by the fact that my feet weren’t being kept warm. This is definitely something to bear in mind if you’re on the taller side. Overall though, there’s a lot to love about the Dreamland and I consider it a worthwhile investment.
