I have the sport seats and find them to be very comfy. It's got some nice side bolsters to hold you in and a leg extension, but lacks the upper back adjuster. There's a lot more sports than ones with comfort seats I feel like (didnt see too many when i was shopping around). Good for long trips, I go back and forth from MI to IL (chicago) a lot and always feel good after the trip. I'm 6 ft 190lbs for a reference pt.
