Does the Queen size have two controls?

Yes. Queen and larger sizes come with dual controllers so each side heats independently.

Will it fit a deep mattress?

It fits mattresses up to 18 inches deep thanks to the fitted skirt.

Yes, it is machine washable. Detach the controllers and cords first and follow the care label.

It is UL certified and designed for overnight use. Follow the manufacturer's instructions and avoid bunching the pad.

It warms the bed from below, which many prefer, but the medium heat level may not satisfy people who want strong, high heat.

The fitted skirt and flexible wiring suit most adjustable bases, but check that the cords have slack when the bed articulates.
