Electric Blanket & Mattress Pads
Research on Electric Blankets
Here are some sites to review. Looks like Sunbeam is the leader in this area. It appears that the blankets are made in US but the controllers are imported. I would guess that is the same for any electric blanket that you would buy.
There is another brand called Frontgate. It’s advertised in several places as “Made in USA” but it wasn’t obvious on the Frontgate web page. So check labels. It’s also likely that the Frontgate blankets are really sunbeam with a different labeling on them. It’s not uncommon.”
