Overview
A king size electric blanket with two independent controllers, a soft flannel-lined polyester shell, and 10 heat settings running from about 87 to 126 degrees F. Built for couples on a shared king bed who each want their own warmth level.
The dual-zone control is the point here: each sleeper sets their own heat level instead of compromising on one shared setting. Continuous sensing hardware is meant to hold that level steady rather than let the blanket run hot in spots, and the auto shutoff timer (1 to 12 hours, your choice) means it won't stay on all night by default.
- 10 heat settings, roughly 87-126°F
- 1-12 hour adjustable auto shutoff
- Dual independent controllers for two sleepers
- ETL and FCC certified, machine washable shell
Who it's for
Couples sharing a king bed with different temperature preferences, and anyone who wants a heated blanket that shuts itself off. Not a fit for someone who wants a small single-person throw or a blanket they can dry clean.
Pros and cons

Performance notes
Insulated heating wire runs through the flannel-lined polyester shell and is monitored by built-in sensing that adjusts to hold your chosen level among the 10 heat steps. The auto shutoff can be set anywhere from 1 to 12 hours, and each side of the blanket has its own controller so the two zones run independently.

Frequently asked questions
Can each side of the Sealy electric blanket be set to a different temperature?
Yes, it has dual controllers so each sleeper adjusts their own side independently across the 10 heat levels.
How long can the Sealy heated blanket run before it turns off automatically?
The auto shutoff is adjustable from 1 to 12 hours, so you choose how long it stays on.
Is this Sealy blanket machine washable?
Yes, but the controller and power cable must be disconnected first, and it should be washed on slow agitation and low spin, never dry cleaned or bleached.
