SIlentnight heated under blanket

This heated underblanket is excellent and particularly good value for the money. Went for the slightly more expensive fleeced lined one which does give more comfort . My previous blanket was a SIlentnight which I had for a number of years without any problems so decided to use the same maker again and am not dissappointed.

5 / 5

best buy of the year

this product works amazingly, you feel the warmth within 30 seconds of switching the blanket on, lower setting means you can use it in summer and higher settings for when its biting cold, the fleece lining helps to retain the heat long after the blanket is switched off. Its easy to use, reliable and adds a little extra cushioning to my bed. After a hard day there's nothing better than jumping into a warm cozy bed. Definitly something to invest in for the whole family. Thank you Argos yet again.

Hi Double,

When lying down the Silentnight Fleece Heated Underblanket's control will be on your right side.

I hope this helps!


Right side. Easy to turn on and off.

in some of the pictures of ur heated blankets they look like fitted sheets which are much better than the ones that tie... can you tell me if all heated blankets are fitted these days or not??? thanks

Hi, thank you for your question.

I have spoken with our supplier who advised this underblanket ties at the edges.

Thank you for using Argos Q & A.


Does this fit a double bed or is it a small square in the middle which I have had before

1 Answer

Go for kingsize, it is little small for 2 people. otherwise is excellent.
