You can customize that heat by using the included controller...

This heated throw blanket has a few settings to truly make it as comfy as you want. The attached controller lets you toggle its heat levels, and it has a timer you can set to turn off as needed, anywhere between 2 to 10 hours. That’s a great safety feature in case you get so cozy, you end up falling asleep with it on, or you’d like to use it overnight. Reviewers say the power cord is long enough to reach even the furthest outlets.

Take note, though: The heating level settings vary by color. The green throw, for example, has nine heating settings, while the beige has five. It doesn’t look like that affects its heating power, and according to some users, the lower-level settings are just warm enough.

...and you can unplug it to toss it in the washing machine.

You don’t have to worry about this getting too dirty or ruining during the rinse cycle — this throw is machine-washable. Just unplug the power cord and controller and you can toss the electric blanket in a cold wash and tumble dry at low heat.
