Climbing in and out of the Navigator's rear seats is easy thanks to the optional power retractable side steps. Our test truck came with the standard rear bucket seats and center console (a bench is optional), and the chairs supplied comfort similar to those in front, though they were mounted a bit low and didn't afford as much leg space as one might expect in a full-size SUV. The third-row, however, is among the most comfortable in any SUV. Here, the Navigator shines in comparison to the Escalade and Escalade ESV. Knee room is a tad tight, but foot space is generous and the bench sits tall off the floor providing plenty of thigh support.
