Slumberdown Wonderfully Warm Dual Control Electric Blanket

Slumberdown's dual-control underblanket is a sensible middle ground between the budget Silentnight and the premium Dreamland. On double, king and super king it splits into two independently controlled heating zones, so one side can run hot while the other stays gentle, with several heat settings each and overheat protection. It's comfortable under a fitted sheet and reasonably quick to warm. The controllers and cabling feel more functional than refined, and like most underblankets it's intended for pre-warming rather than all-night use, but for couples wanting proper side-by-side control without paying top money, it's a solid buy that resolves the perennial thermostat argument.
