Why it sits behind the Silentnight Luxury Hotel Collection Electric Blanket

The Silentnight Luxury Hotel Collection Electric Blanket (8.7) beats the Wärmer Electric Blanket Double Dual Control Fitted (8.6): owners are about as happy with both, and it is the newer design.

About the Wärmer Electric Blanket Double

The Wärmer Fully Fitted Electric Blanket sits on top of the mattress like a fitted sheet. It has an elasticated skirt of 40cm, so it stays put without straps or ties. The double measures 193 x 137cm and is made from 100% polyester.

Each side of the bed has its own detachable controller with three heat settings, so two people can sleep at different temperatures. Both sides draw 60W, which makes 2 x 60W for the double. It runs on 230V. The brand says it has overheat and overcurrent protection that works from the first plug-in and shuts the blanket down if it overheats or gets too much power.

The brand says it is machine washable at 30°C, and the controllers detach for that. The brand's page gives no box contents or manual details, so check the listing for what comes with it. The brand also lists a 365-day warranty, which it says covers the product "in the unlikely event that this product is at fault".

What owners report about the Wärmer Electric Blanket Double

We found little owner feedback that names this exact double model, so what follows is limited. The feedback we found is on the brand's wider fitted blanket range, on a customer-review page for the brand's website.

Owners of the brand's fitted blankets generally say they fit well, including on deeper mattresses, and that they heat up quickly and are comfortable to sleep on.

The recurring complaint is the controllers. Several owners report controllers that overheat or stop working, some within months, and some say replacements failed too. Some also say the company was slow to answer emails about faults or returns. Treat the warranty as something to register and keep paperwork for.

Who the Wärmer Electric Blanket Double suits

It suits couples sharing a double bed who run at different temperatures, and anyone who is tired of strap-down blankets creeping around the mattress. The skirt covers mattresses up to 40cm deep. Two sockets near the bed are needed, one for each controller.

Look elsewhere if you have a single, king or super king bed, since this listing is for the double only. If you want a timer, the GlamHaus Double Electric Blanket Fitted Quilted has one. For a single bed, the Russell Hobbs Fitted Single Electric Underblanket is the better fit. Expert Reviews also says manufacturers often advise against heated pads on memory foam mattresses, so check your mattress maker's advice first.

How we score it

Every score here comes from our ranking model; no editor sets the order. Too few review sites cover electric under-blankets for their verdicts to lead, so this ranking is led by owners. It ranks products by how happy owners are, holding back any product few owners have rated until more agree. How many rated it and how new it is only settle close calls, and value for money earns its own badge rather than a higher place. We compared 26 models for this guide before settling on these ten.

Brands can't pay to be included or to move up. We last checked these picks in October 2026.
