Winter is not far off and this will make it much more tolerable. Everyone should have one.

Don’t get any audio and the picture quality is dreadful.

I use a heated throw which is like an electric blanket used on the big armchair with stool and can be used on a couch etc.

Another obvious alternative which would be easier if you want a heated chair is to get one used in cars from a wrecked car from the wreckers.

Wow. I don't know how he didn't foresee the problem of sitting right on the coils. And it has a 220V plug!

I have used a heating pad / inverter to make a heated seat in the car. Some heating pads don't like inverters, so test this in advance.

More likely the inverter doesn't like the heating pad. Heating pads are a "pure resistive" load.

but the controllers are not.

some new heating pads have electronic controls that will not work correctly with a square or quasi square wave inverter output.

Which appears to be what happened with the first heating pad I tried on an inverter. There was no heat, just a flashing LED on the controller. A different heating pad worked OK on that same inverter.
