TrueDelta Reviews the Seat Room and Comfort of the 2014 Lexus IS

2014 Lexus IS Seat Room and Comfort: Pros
YearComment
2014 Following the Germans' lead, many car makers have been fitting firmer and firmer seats. Cadillac might have once been known for seats you could sink deep into, but those in the ATS are the opposite, with too little give and contours that are far from form-fitting. No fear, Lexus hasn't done the same with the IS. Even the more heavily bolstered seats that are part of the F Sport package lack hard points, which helps them provide a slop-free fit for a wide range of body types. (Oddly, you'll find seats similar to these in some Chrysler people haulers.) Personally, I wouldn't mind a little firmer support, but then I also prefer a firm mattress. Notably, the lumbar support in the Lexus IS is only two-way and the spread of the side bolsters is not adjustable. For four-way lumbar support and adjustable side bolsters (plus somewhat firmer support) you need to step up to the larger Lexus GS. see full Lexus IS review

2018 Audi A4 / S4 Seat Room and Comfort: Pros
YearComment
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

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
