Double electric over blanket

[abstibus]

Can anyone suggest one of these that does not slither around? It would be good if it had an extra bit that could be tucked in. Alternatively, could someone recommend an all-night under blanket? I'm planning ahead.

I bought an underblanket from Boots a few years ago. It's a double one, but I only need one side, and it's got separate switches. It's been great.

Best I had was an underblanket that had corners like a fitted sheet so it stayed in place.

Thank you both. Lankeela, do you know what make/model it was or where you got it? Can it be left on all night?

I had to buy an double overblanket when my husband was ill. I safety-pinned the top corners (well away from any electrical wiring) to the top corners of the duvet and placed the whole inside the duvet cover - never had any problems with it moving and it is still going well 8 years later.

That's a great idea. I used one for the first time last winter and it moved around so much that I took it off.
