Measure carefully - double v king-size.
I bought the king size which is a perfect fit for my DOUBLE mattress. No cold feet or shoulders. Be careful to measure your mattress carefully as once you've opened the packaging the item cannot be returned.

Nice and cosy
I brought this electric blanket as my other one stopped working. I am very pleased with this purchase, it is comfortable and gets nice a warm with four settings. We brought this for our double size bed as we wanted warmth all over. I would recommend this and a well known brand.

Very comfortable. Doesn’t wrinkle
Bought to replace an old electric blanket. Delighted with it. Has one control which suits us as my husband has dementia and wouldn’t remember how to put it on and off. Very nice and soft. Doesn’t wrinkle or move. Perfect

Not the best for warmth
This was a quick purchase as my other had broken. It’s okay but not as warm as my previous one. As they say, buy in haste…..

Hello Priya,

3 meters in length.
Thanks for using Q & A.
Hello Pam,
After checking with our supplier, they have advised for the Silentnight Comfort Control Electric Underblanket - Kingsize: Our electric blankets are not thick, approximately 0.2cm. For extra comfort, the electric blanket can be covered with a protector/thin topper. All Silentnight products are safe to use with an electric blanket however other brands would need to be checked with the manufacturer directly.
Thank you for using Q&A.
Hello there,

Hello Sal.
Silentnight Comfort Control Electric Underblanket - Single:
Once you’ve picked a heat setting, the sensor fine-tunes the output to prevent overheating or sudden drops in warmth.
For example, if the room gets colder, it might boost the heat slightly to maintain comfort—but only within the range of your selected setting.
So the point of having both is personal control + smart adjustment. You get to choose the intensity, and the blanket helps keep it steady and safe.
Thank you for using Q&A.

Hi Snorer,
Yes, it is generally safe to use the Silentnight Comfort Control Electric Underblanket on top of a memory foam mattress topper. However. Always follow the manufacturer's guidelines for both the electric blanket and the memory foam topper. This ensures you are using the products safely and as intended.
Thank you for using Q&A
Hello Happy Camper,
The supplier has advised the following for the Silentnight Comfort Control Electric Underblanket - Kingsize:
“ Our electric blankets are intended to fit where your pillows end and run to the bottom half of the mattress. The blanket will also be a few inches short of the edges of your mattress, this is to ensure, once flat on to the mattress, the blanket will stay in place. The sizing of the electric blankets is for safety reasons, it ensures the blanket stays in the correct place and that the wires are not damaged, the blanket needs to be strapped down and remain flat with no creases to ensure no heat spots.
Due to these reasons, we would not recommend using a king-size electric blanket on a super-king size bed. ”
Thanks for using Q&A.
Hello Jac,
The Silentnight Comfort Control Electric Underblanket - Kingsize 450/0434 can be used upside down and turned around. There is no top or bottom. Always ensure it is flat and strapped down and the controller is not covered by covers or pillows.
Thanks for using Q&A
Hello there,
The supplier has advised the Silentnight Comfort Control Electric Underblanket - Kingsize cord is approximately 2 metres from the controller to the blanket fitting.
