Subaru decided to drop five-seater Tribecas for the 2010 model year, which means every 2010 Subaru Tribeca now offers third-row seating as standard. While this may initially seem good, the third-row seat is very tight and presents outward visibility problems.
Otherwise, the interior of the 2010 Subaru Tribeca is very pleasant. Kelley Blue Book praises "the wide front seating, which also features adjustable lumbar support for both the driver and passenger." They also applaud the "excellent fit and finish," saying the "appealing materials and an uncommon dash design are the hallmarks" of 2010 Subaru Tribeca. Some drivers, however, may find the lack of a telescoping steering wheel a problem, as noted by the reviewer at Cars.com: "it only tilts...my arms grew sore from stretching to reach the wheel."
The 2010 Subaru Tribeca is only a mid-size crossover, so it’s not as large as other SUVs with three-row accommodations. As a result, the third row is cramped for all but small kids, and while the second row moves fore and aft by eight inches, it, too, becomes cramped when making room for the third row. Edmunds complains that the second row, "although fine for kids, lacks the legroom and hip room that larger, taller adults need." The second-row seats do recline and are split 60/40, and big grab handles ease access to the third-row for kids.
A common problem with the third-row seating is rearward visibility. Cars.com notes that, "over-shoulder visibility is decent, but the Tribeca's large A-pillars can hide pedestrians and even cars when they're on the right-hand side."
Finally, MotherProof finds "plenty of functional storage in the Tribeca," including several cup holders and storage bins.
