Beautyrest plush electric blanket. We've tried a few over the years - this was recommended because of the low emf (electric blankets create an electric field - this one less.) You don't want a throw, because they usually go off after 3 hours. We bought one for our old kitty, and we love keeping the house cooler. It has up to 10 hours before it shuts off. We bought a second one this year, for a guest bed. https://www.target.com/p/plush-electric-blanket-beautyrest/-/A-51435195?preselect=51389066#lnk=sametab
