Adjust the position of your neck, too. This unique adjustment gives you the ability to keep your head and neck in the most comfortable position. Neck adjustments keep your upper body positioned so your spine is aligned for just the right support. Need something more? From the hand remote, you can also maximize comfort with a zoned massage feature that allows you to massage upper or lower body or both at the same time. You'll also find programmable and pre-set positions for enjoying the same positions of comfort. Adjust Zero G to lift legs for better circulation. Use the TV adjustment to position your head for cozy TV viewing and the Snore adjustment to slightly raise head to help open up airways. Plus, the motion-sensor under-bed lighting is especially useful. As you get out of bed, the floor will become softly illuminated. Two USB ports are available for connecting electronics—what a plus for convenience.
