Price and rating as shown on Amazon when we collected them. Both change.

The Sleepy Nights is the cheap small-single option here, and the listing covers its essentials: three heat settings, a washable cover, a two year guarantee and BEAB approval with sleep safe overheat protection, in 100 per cent polyester with a fleece fill, in white.

BEAB approval is the term to look for on a heated underblanket, because it is an independent safety approval for electrical household goods sold in the UK rather than the manufacturer's own assurance. Three heat settings is the minimum sensible count. At the time of collection it carried 2,686 ratings at 4.3 stars. Everything here comes from the Amazon listing rather than our own testing.

What buyers actually say

Quoted from customer reviews on Amazon

“I've never had an electric blanket before and tbh was a bit scared of them, I had been warming my bed with a hairdryer for a long time. I decided on this one and so glad I did, it fits really well, doesn't move at all, it takes 20 mins to warm my bed to a really comfortable temperature, and stay warm too, so easy to operate and after my initial worry I am gaining confidence in using it, I use it with a microfibre fitted sheet on top but I imagine if you had something like a teddy fleece fitted sheet or a mattress topper on it it would take a while to warm up the bed. Also, even though I can feel the thin wires with my hand if I touch it I can't when I'm actually laying on it, it has a lovely warm fleecy feel as well, I'm very happy with my purchase indeed”

“Fully covers the width of our king size bed. I am officially blind with a less than 5% of my usable vision available. I was able to unpackage the product and put it on the bed with the easy straps which come with the blanket. The only thing I couldn't do was to read the instructions. However I simply found the maximum setting on the switch and plugged it into a Wi-fi plug so now I get Google to turn it on and off which is great when you got your head underneath the duvet snuggled up warm the last thing you want to do is put your hand out into the cold to switch the blanket off. I would say it's a little bit slow to really get up to top temperature but once it's there it really holds its heat so well. we give it about 30 mins to heat up fully. Certainly much easier to instal and keep centralised on the bed with the straps rather than those messy little strings which always got knots in them and never really worked properly.”
