What Our Members Are Saying about the Seat Room and Comfort of the 2012 Infiniti M

2012 Infiniti M Seat Room and Comfort: Pros
YearBody/PowertrainComment
2011 4dr Sedan 420-horsepower 5.6L V8
7-speed shiftable automatic AWD
Very comfortable up front. see full Infiniti M review
2011 4dr Sedan 330-horsepower 3.7L V6
7-speed shiftable automatic AWD
The footwells are very narrow for a car of this size. This is a side-effect of it being RWD. The "dead" pedal seems to be in the wrong spot, at least for me; it's too far to the right. On the plus side the air conditioned seats are great. It is possible to drive around in 90 degree weather wearing shorts, with the windows down, and feel comfortable. see full Infiniti M review
2011 4dr Sedan 330-horsepower 3.7L V6

Very envelopped and comfortable seat, have better padding, and seating posture is better than most of the luxry cars I tried. see full Infiniti M review

The fronts seats need more bolstering. The BMW 5 series has much, much better seats. If I could change one thing about the car, it would be the seats. Anyone considering this car should sit in the seat at least 30 minutes before making a purchase decision. see full Infiniti M review
 

TrueDelta Reviews the Seat Room and Comfort of the 2017 Lexus IS

2017 Lexus IS Seat Room and Comfort: Pros
YearComment
2016 For me, the front bucket seats in Lexus F Sport models provide a nearly ideal blend of comfort and support. Even when they don't lack lateral support, the seats in competitors don't fit my form as well. Infiniti doesn't offer the Q50 2.0t in Sport form. The standard car's front seats provide little lateral support. The instrument panel appears larger and more imposing in the Infiniti than in the Lexus. Still, I wish the view forward were a little more open in the latter. (The Cadillac ATS is better in this regard.) Lexus lowered the driving position compared to the previous IS to help the car feel sportier. I raised the seat some to compensate. Adding all-wheel-drive to the Lexus IS (and a V6 engine with it, AWD isn't offered with the 2.0T engine) adds another issue, a large hump beneath the driver's right calf. Some drivers might find they have to adjust how they sit to avoid this hump. see full Lexus IS review
