TrueDelta Reviews the Seat Room and Comfort of the 2013 Infiniti JX

2013 Infiniti JX Seat Room and Comfort: Pros
YearComment
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

2014 Acura MDX Seat Room and Comfort: Cons
YearComment
That's it for the significant advantages of the new Acura MDX. Most things it does well, but not significantly better than the generally good segment averages. It's quick, but not thrillingly so. The front seats are comfortable and supportive, and cushier than those in the Infiniti, but provide less lateral support than those in the smaller Acura RDX and are no match in comfort or support for those in a BMW X5, a Lexus RX, or the big buck Mercedes reviewed a few weeks ago. Ride quality, like the seats, is good but short of luxurious. With additional sound deadening and laminated front door glass, the 2014 MDX is quieter than the 2013, but this only brings it in line with the others. By the same token, there aren't many clear reasons to reject the 2014 MDX. The most obvious follows from its relatively compact size: though (as already mentioned) cargo volume is more than competitive, there's less room in the rearmost row than in the QX60. By sliding the second row up a couple of inches (it has a half-foot of travel), adults of middling size will fit back there. But with their butt low and knees high they won't be comfortable. The QX60 offers far more combined legroom based on the spec sheets, and a couple more inches in the real world. (The Acura's specs seem to under-represent reality for passengers even as they might over-represent it for cargo.) But the Infiniti's seats are flatter and less comfortable. The new Hyundai Santa Fe offers more legroom than the Infiniti, while Ford's large crossovers could be best of all for transporting up to seven adults--if still not as good as the typical minivan. see full Acura MDX review
