Overview
This king-size Westinghouse blanket layers double 220 GSM flannel over ETL/FCC-certified overheat protection, with 10 heat levels and a 1-12 hour auto-off timer.
At 100 by 90 inches it's sized for a king mattress, and the two-part cord (72 plus 156 inches) suggests separate connections for each side of the bed rather than one shared controller, common on king-size electric blankets so two sleepers can each pick their own heat level. It machine washes, but only after the controller is unplugged and removed, and the brand is explicit that it should never be run while damp, or be bleached, dry cleaned, or ironed.
- ETL/FCC certified overheat protection
- 10 heat levels, 1-12 hour auto-off timer
- 220 GSM double-layer flannel
- Machine washable, controller detaches first
Who it's for
Suits a couple sharing a king bed who each want independent control over warmth, or anyone wanting a washable heated blanket with a real auto shutoff rather than one switched off by hand. Less suited to anyone who prefers a single shared control or a lighter throw-weight blanket.
Pros and cons
- ETL and FCC certified overheat protection
- 10 heat levels with 1-12 hour auto-off
- Machine washable once controller is detached
- Double-layer 220 GSM flannel construction
- Cannot be dry cleaned, bleached, or ironed
- Must fully dry before it can be reconnected
Performance notes
The overheat protection and ETL/FCC certification govern how the blanket behaves if the resistance wire gets crumpled or pressed against for too long, cutting power rather than continuing to heat. The 1-12 hour auto-off timer and 10-level heat control let it run unattended overnight without needing to be switched off by hand, and the maker recommends level 3-6 for typical cold-weather warmth rather than running it at the top setting.
