Throw vs. full-bed electric blanket — which should I buy?

A 50"x60" heated throw is the consensus pick for couch use, reading, and personal warmth, and it's the size most reviewers test. A twin, queen, or king bed-sized blanket (often with dual controls) makes more sense if you want it tucked under a duvet, and dual-zone controllers are the feature couples consistently call out as worth paying for.
