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 2003 Ford Mustang
Front seats are not particularly comfortable but not so different from most cars I've driven. I've already bought seat cushions. I've put long days on a bicycle I ride regularly which is more comfortable than anything between a vintage VW Beetle and a modern Buick with the exception of a Renault 16. In fact most car makers would do well to go out and find a 1972 Renault 16 and take very, very careful note of the seats.
But seat comfort was secondary to other considerations such as water-tightness of the convertible. Not a deal-breaker.
