How does dual-zone control work?

The Queen size has two controllers, one for each side of the bed, so each sleeper sets their own heat level. Smaller sizes use a single control.

Will it fit a thick mattress?

Yes. The attached skirt stretches to fit mattresses up to 21 inches deep.

Yes. Unplug and remove the controllers and cords, then machine wash and tumble dry. Reconnect everything once it is fully dry.

It goes directly on the mattress, under the fitted sheet, so the warmth reaches you through the bedding.

It warms the mattress from below and stays flat under the sheets. A heated blanket sits on top and can be used away from the bed.

Twin, Full, Queen and California King. Dual-zone control comes with the larger sizes.
