2014 Kia Optima Seat Room and Comfort: Cons
Year	Comment
	The Optima's rear seat is comfortably shaped, and includes plenty of room for passengers to stretch out their legs. Heads are a different matter. Though I'm only 5-9, if I still had much hair it would have been brushing the headliner. The Fusion provides a little more rear headroom, but less knee room. Buyers seeking a rear seat suitable for large adults won't be happy with this aspect of either car. see full Kia Optima review
