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

2012 Lexus RX Seat Room and Comfort: Pros
YearComment
2013 Lexus have also tended to be more comfortable than competitors. The front seats in the RX are generously sized and very comfortably shaped. They're softer than those in competitors (the Cadillac SRX's buckets are borderline hard), yet are properly supportive. Though the side bolsters aren't large--only the upholstery, black with white perforations, differs from the regular RX 350--lateral support is sufficient for how the Lexus asks to be driven (we'll get to this). see full Lexus RX review
2012 Lexus RX Seat Room and Comfort: Cons
YearComment
Probably because they were designed to fold in a single step to form a nearly flat floor, the 40-20-40 rear seats in the RX 350 aren't nearly as comfortable as the front seats. Passengers have plenty of room, but the seat cushion is too low to provide adults with thigh support and the seat back is too flat. The rear seat in the SRX isn't as roomy, and isn't much more comfortable. But I'd much rather spend time in the back seat of some other competitors. see full Lexus RX review
