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

2017 Lexus IS Seat Room and Comfort: Pros
Year	Comment
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

What Our Members Are Saying about the Seat Room and Comfort of the 2009 Infiniti G

2009 Infiniti G Seat Room and Comfort: Pros
Year	Body/Powertrain	Comment
2010	4dr Sedan 328-horsepower 3.7L V6 7-speed shiftable automatic RWD	Spacious and comfortable seats see full Infiniti G review
2008	4dr Sedan 306-horsepower 3.5L V6 5-speed shiftable automatic RWD	I love the roominess of the rear seats. Most of my family are moderately large (6ft 220lbs). Two can fit in the back comfortably. see full Infiniti G review

2009 Infiniti G Seat Room and Comfort: Cons
Year	Body/Powertrain	Comment
2010	4dr Sedan 328-horsepower 3.7L V6 7-speed shiftable automatic RWD	Smaller than the Maxima. Third person would be uncomfortable, less knee room. The plastic trough behind the front seat is too low. see full Infiniti G review
2010	2dr Hardtop conv. 325-horsepower 3.7L V6 7-speed shiftable automatic RWD	The rear seat is basically a storage area. No one can sit back there! But its really no different than the rear of any convertible. (like my Mercedes Benz CLK350) see full Infiniti G review
2010	4dr Sedan 328-horsepower 3.7L V6 7-speed shiftable automatic AWD	Seats in back are cramped. Once the kids hit teenage years they are not going to be happy back there for long rides. see full Infiniti G review
2010	4dr Sedan 328-horsepower 3.7L V6 7-speed shiftable automatic RWD	Seems smaller than the G35, no rear reclining seats anymore and the headrests stick up a bit more than the old car. see full Infiniti G review
2009	2dr Coupe 330-horsepower 3.7L V6 6-speed manual RWD	The bolstering is excessive in the lowest setting and the seat belt pulls too hard on my chest. The seat belt also digs into my neck. see full Infiniti G review
2009	2dr Coupe 330-horsepower 3.7L V6 7-speed shiftable automatic RWD	Way to small to be of use with anything but children. see full Infiniti G review
2009	2dr Coupe 330-horsepower 3.7L V6 7-speed shiftable automatic AWD	Tight on head room but to be expected for two door. see full Infiniti G review
2008	2dr Coupe 330-horsepower 3.7L V6 5-speed shiftable automatic RWD	there is hardly any back see room but it is a sport coupe see full Infiniti G review
2008	4dr Sedan 306-horsepower 3.5L V6 5-speed shiftable automatic RWD	Very tight see full Infiniti G review
