The Veloster is setup like a sports car - stiff suspension, low riding height, and sport seats designed to keep you in place. What this car is not is comfortable. At all. There is almost no back support, and little coushining. On a long trip, it will be PAIN. On roads trampled on by dinosaurs, it will be PAIN. The interior accents also get in the way of resting your legs on anything, so you have to just deal with the space provided, which isn't much. This car is just big enough, and not a milimeter more.

What Our Members Are Saying about the Seat Room and Comfort of the 2014 Nissan Frontier
The driver's seat feels nice and comfy, even after two or three hours of driving. Not too much pressure under the legs by the knees, and not too little lumbar support. I imagine the passenger's seat is the same, but I so infrequently sit there I can't really comment.

I only rode in the back a couple times. Keep in mind, this is not a full-sized truck.
The legroom isn't much, but sufficient for a smaller adult or, if you keep the trip short, most anyone. The seat isn't really wide enough to comfortably sit 3.
Also the seating position is very upright - like church pew upright. I was not a fan, but I never sit back there anyway. :)
