The Suburban’s second-row bench sits lower than expected, but is dished for good thigh support. Rear seat leg room is tighter than it should be in a vehicle this large, but only when tall people are riding up front. The third row is not comfortable for adults, about on par with a typical minivan. I managed to ride in moderate discomfort on a journey from Santa Barbara to Los Angeles – about 100 miles in 90 minutes. It is a seating position to be endured. Leg and foot space are tight and the seatback is too vertical for comfort. Tumble the second-row seats and the third-row transforms to limo-like comfort.
