TrueDelta Reviews the Seat Room and Comfort of the 2014 Kia Optima

2014 Kia Optima Seat Room and Comfort: Cons
YearComment
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

TrueDelta Reviews the Seat Room and Comfort of the 2015 Toyota Sienna

2015 Toyota Sienna Seat Room and Comfort: Pros
YearComment
2015 The Sienna's seats are cushier than those in the Odyssey or the Sedona. But I slightly preferred the Sedona's front seats because they had four-way lumbar (rather than two-way) and provided more lateral support. The Toyota earns a clear win in front seat space. The first-row foot wells are unusually wide, and there's no tall center console (as in the Kia) or a protruding center stack (as in the Honda) to crowd the driver's right elbow or knee. This said, a relatively tall instrument panel does cut into the view forward and contribute to the Sienna feeling larger than the others. see full Toyota Sienna review
