Electrowarmth used to make a queen sized version. I have one and like it a lot, but I think there's a reason they don't make any larger than twin sized any longer. I suspect the larger pad was pushing the limits of the standard 12v sockets found in auto and RV use. The plug Electrowarmth uses on the end of their cord is a good quality phenolic, but plug it into a cheap socket that doesn't hold it tight enough and it will get hot. When I noticed that on mine I replaced the Elecrrowarmth 12v plug with a Marinco plug and receptacle on a dedicated circuit with 6 gauge wires.

My 12v pad in the camper works just as well as my 120v pad at home. If mine ever needs replacement, I intend to buy two of the twin size pads and sew them together to make one pad of 60"x72", which is perfect for a queen mattress. The two twin pads would be running across the width of the mattress, but that's OK. You typically want the leg/feet area to be warmer than the chest area anyway, and the head area to not be heated at all. I'll have to add another receptacle since there would be two controls. As far as I'm concerned the best things about the Electrowarmth pads are the analog control, and no expensive PSW inverter required.

When we travel in the winter, I run it on a low setting while we drive to keep the mattress over the cab from turning into a block of ice. I've also got heavy gauge charging wires running from the truck alternator, so it's able to keep up with the draw from the mattress heater.
