2013 Mercedes-Benz GL Seat Room and Comfort: Pros
Year	Comment
2013	The Mercedes-Benz GL-Class is just a little longer than the Audi Q7 (201.6 vs. 200.3 inches), and isn't as wide (76.4 vs. 78.1 inches). But the Mercedes is considerably taller (72.8 vs. 68.4 inches) and not nearly as curvy. Which might explain how it is far roomier than the much sleeker Audi. Combined legroom for all three rows is 107.6 inches in the Q7 vs. 113.8 inches in the GL-Class, a large difference. The Q7's space deficit grows the farther back you sit. For adults to even fit in the Audi's third row without extreme discomfort, those in the second row must slide their seats forward to the point that they are themselves short on knee room. While the new GL350's third row sits too low to provide thigh support, it's not nearly as cramped. Further evidence that Audi didn't intend the Q7's third row for frequent use: the second-row seat doesn't do a good job of getting out of the way, making the path in and out of the way-back perhaps the tightest I've experienced. The second-row seat in the GL-Class tips forward to open up a much wider path. If manually tipping the seat is too much of a chore (perhaps because you'e a five-year-old and haven't yet learned to read this), $400 buys a power assist. But even with this option the seat must be manually returned to its upright position, so the point eludes me. see full Mercedes-Benz GL review

2018 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

2018 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
