Does it heat both sides of the bed separately?

No. It is a single-zone pad, so the whole surface runs at one setting. Couples who want different temperatures should look at dual-control pads.

Can it go in the washing machine?

The pad is polyester fleece, but the heated element and controller mean you should detach the controller and follow the care label. Most heated pads are machine washable on a gentle cycle only.

Does it have an auto-off timer?

No timer details are published for this model. Brand-name pads such as Sunbeam usually offer a timed shutoff, so check the controller before relying on one here.

Will it fit a standard king mattress?

At 78 x 80 in it matches a standard king mattress top. It is a flat pad, so it lies under the fitted sheet rather than wrapping the mattress.

How does it compare with a Sunbeam heated pad?

It offers a larger single-zone surface and soft fleece, but Sunbeam pads typically add dual controls, timed shutoff and more heat settings. Choose this for simple all-over warmth.
