2008 | 4dr Sedan 303-horsepower 5.3L V8 4-speed shiftable automatic FWD |
Front of the GXP is great - heated leather seats, plenty of seat adjustments, and the controls are all pointed at the driver. Even on a 20 hour trip, I had no issues with discomfort. see full Pontiac Grand Prix review |

2013 Infiniti JX Seat Room and Comfort: Pros | ||
Year | Comment | |
2013 | I'm struggling to come up with a fifth reason for buying the Infiniti JX. Not because the rest of the vehicle is bad, but because in the great majority of aspects it's neither notably good nor notably bad compared to competitors. They're all fairly quick, smooth, and quiet. If I have to pick a fifth reason, then it's third row room and comfort. A Buick Enclave has a roomier third row, but both the Acura MDX and the Audi Q7 do worse. This said, the second row must be slid forward to provide legroom to people in the third row. The seats in both rearward rows are of the low-mounted, flat-cushioned variety typical of the segment, so they're not very comfortable for adults. You'll find a more adult-friendly second row in some large crossovers, especially those from Ford and Lincoln. see full Infiniti JX review |

Amazing rear seat comfort and even 3rd row seats are awesome!! I am 6'4" (with a longer torso) and I can get in the car easy, and sit comfortably in the 3rd row!! Great DVD system and air climate control for the rear seated passangers. see full Infiniti JX review |

Awesome. Great layout of everything. The most comfortable seats I have ever sat in. Great for long drives over 3 hours. I wish my Toyota 4unner seats were as comfortable; they are only good for about 1 hour, max. see full Infiniti JX review |
