Dreamland Snowed In Warming Mattress Protector Review

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

I have no hesitation in saying that this is one of the best electric blankets I’ve tested, aside from a few minor hiccups. I tested both the single and double sizes with dual controllers – here’s what I thought of both.

Dreamland Snow in Organic Cotton Warming Mattress Protector: What do you get for the money?

The Dreamland Snowed In Warming Mattress Protector is made from a 200 count organic cotton cover and 100% polyester fiber filling, with a large stretch skirt that will fit mattresses up to 38cm deep. There are six heat settings and three timer settings, as well as overheating protection and automatic shut-off. Like the Dreamland Heated Duvet I recently tested, the cover is both machine washable and safe to tumble dry – although you’ll need to drop it on a low surface and take it out of the water to dry it flat.

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

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

The heated underblanket is less expensive than Dreamland’s Hunker Down Scandi Sherpa electric blanket (£115) and the Beurer Indulgence Heated underblanket (£100), both of which are doubles and twin controls. In this case, the Hunker Down is a traditional electric blanket with straps to attach it to the mattress, while the Beurer has a skirt design. Cheaper options are available, such as the Silentnight Comfort Control electric blanket for £35 (or, if you still want two controls, the Your & Mine blanket for £40 for a double), but these usually don’t cover all mats.

The Dreamland thermal 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 test like you do with other brands.

Comfort, performance and test results

When I test thermal blankets and throws, I always test the same to see how they work against each other. The Dreamland Snowed In Warming Mattress Protector performed very well when it came to my temperature test.

After taping the temperature probe to the resistor (placed next to one of the heating wires), I recorded the temperature rising for over 10 minutes. After 10 minutes on full power (setting six), the protector had reached an incredible temperature of 54°C, which rose to 58°C when I repeated the test with a duvet on top. At half power (three settings), it reached 27.2°C after 10 minutes – a good result, but not as warm as the Beurer Indulgence (29.8°C).

After an hour of heating, I again checked the temperature on the protector with an infrared thermometer gun. Again, the results were positive, with temperatures reaching 47°C upwards. In the lower left and right corners, the results were slightly lower at 30.5°C and 29.8°C respectively (more on that later). Finally, I also ran some power consumption tests to see how well Indulgence works. At full power the blanket used 35W of heat and 0.020kWh accumulated after 30 minutes. At half power, these readings were 30W and 0.015kWh respectively. Excellent results considering its high temperature at full power.

As far as real life testing goes, I absolutely loved sleeping on the Dreamland Snowed In Organic Cotton Warming Mattress Protector. Temperatures were impressive at full power, and warmed up quickly – even if Dreamland’s five-minute heating claim is a little optimistic: I’d give it 10 minutes at least. As a lightweight, I tend to feel electrical cords, which can be a little uncomfortable. However, perhaps due to the thickness of the padding, I did not feel any strings here.

On top of all this, you can keep it open during the summer as a regular mattress protector, with the cords closed, which helps protect your mattress from dirt and spills. Note that it is not waterproof but, as I explained above, it is easily machine washable.

Logically, the Dreamland doesn’t get hot under the pillow area, and the natural cotton cover means the cover is really breathable – something my hot sleeper husband appreciates as he keeps his side of the cover firmly closed!

What can be improved?

I had a few issues with the Dreamland, the main one being the brand’s inexplicable choice not to extend its cables all the way down to the fender area. I found that, as a tall person, this didn’t do me any good when it came to keeping my feet warm – much to my chagrin.

I also didn’t like the placement of the controller connectors, I feel they are too low on the floor (could be better hidden under a pillow), and the raised connector area feels uncomfortable if you accidentally roll over it.

Should you buy the Dreamland Snowed In Organic Cotton Warming Mattress Protector?

This is a great electric blanket: it’s comfortable to sleep on, it produces amazing heat and I love 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 the most expensive option, and I was annoyed that my feet weren’t warm. This is definitely something to keep in mind if you are on the long side. Overall, there’s a lot I like about Dreamland and I consider it a worthy investment.
