Programmable electric underblanket

[Dilbertian]

I'm looking for an electric underblanket that can be programmed to come on at certain times. All the 'programmable' blankets I can find are ones that preheat the bed. I want one that will switch off after an hour or two, and then switch on again 5 or 6 hours later.

Anyone have something like this?

Could you go for a regular blanket and a timer plug?

I've considered that, but the sockets are out of reach behind furniture. A timer switch would also add extra bulk, so I don't know whether it would fit. I'd like to have the flexibility of being able to change settings easily, which means being able to reach the controls - preferably from in bed.

We have one with a 1hr or 9hr time out - would that work for you?

Does 9h mean it stays on all night?

Attach to a plug controlled by Alexa ?

No Alexa.

If I can't find a blanket which can be programmed to come on again after a few hours, I may have to go down the programmable timer plug route. But that meat require an extension as well. Clumsy and messy solution.

Yes, 9h would stay on all night.
