2016 Audi A4 / S4 Seat Room and Comfort: Pros
Year	Comment
2017	Before the 2009 model year redesign, the Audi A4's back seat was too tight for adults of more than average size, and marginal even for these. With the 2017 the back seat has grown yet again. Not only this, but the cushion is higher off the floor than in previous A4s or in competitors, such that it's now the most comfortable in the class. This said, the rear doors could open more widely, such that I struggled to get a decent photo of the rear seat. Since its 2014 model year redesign the Lexus IS has had a passably roomy rear seat, but it can't match the Audi's for comfort. see full Audi A4 / S4 review

2016 Audi A4 / S4 Seat Room and Comfort: Cons
Year	Comment
	Pressed to come up with another con, I might offer the front seats. There's nothing bad about them. There's just nothing outstanding about them, either. Those in the sport-trim Lexus provide more lateral support and feel more comfortable to me. (With seats personal impressions are bound to vary, so definitely evaluate them yourself.) see full Audi A4 / S4 review

2010 Infiniti M Seat Room and Comfort: Pros
Year	Body/Powertrain	Comment
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 7-speed shiftable automatic RWD	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
2009	4dr Sedan 325-horsepower 4.5L V8 5-speed shiftable automatic AWD	Huge rear seat with tons of space. Passengers routinly comment on how comfortable it is. Significantly more rear seat room then 5 series BMW. Ininiti G35/37 has more rear seat than the 5 series. see full Infiniti M review

2010 Infiniti M Seat Room and Comfort: Cons
Year	Body/Powertrain	Comment
2011	4dr Sedan 330-horsepower 3.7L V6 7-speed shiftable automatic AWD	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
