Most reviewers find the 2009 Infiniti EX35 satisfactory in terms of comfort and quality, though space is indisputably tight.
Front seats in the 2009 Infiniti EX35 garner neither raves nor rants (AutoWeek says, "It features high-quality materials and superbly comfortable seats"), but rear space is at a premium. "The EX35's greatest interior shortcoming is the size of its backseat," Cars.com comments, "which is especially frustrating, because the lack of space seems unnecessary." Motor Trend points out that compared to the Acura RDX, "Rear-seat legroom, at 28.5 inches, pales to the 37.7 in the RDX." Edmunds reports "solid ergonomics" all around. Some key ergonomic features, however, aren't included in the base EX35.
Cargo space is also tight in the 2009 Infiniti EX35. Motor Trend states that the "meager 16.8 cubic feet of cargo volume (only 3.3 more than that of a G35) is down by a couple of Miata trunks compared with the Acura's 27.8."
As far as materials are concerned, AutoWeek "found the interior extremely pleasant. It features high-quality materials and superbly comfortable seats." Cars.com mentions that "aluminum trim appears sparingly and is effective, as is the black-lacquer bezel on the center console and control panel." These are standard in the base model of the 2009 Infiniti EX35, but Edmunds reports that "the optional maple wood trim is much nicer." Edmunds adds a caveat: "interior materials aren't going to win any awards for quality," but those who are willing to pay extra can have genuine leather upholstery. Cars.com, however, remarks that "the interior is appointed like other Infiniti models... with modern, high-quality materials."
