Raise your upper body too and sit up in bed for better breathing, essential for those who snore or experience acid reflux. Need something more? Maximize comfort with a zoned massage feature found on the remote that allows you to massage upper or lower body or both at the same time. Plus, use the helpful under-bed lighting feature to softly illuminate the floor so you can get around in the dark. Two USB ports are available for connecting electronics—what a plus for convenience.
