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
