The 2013 Murano has a comfortable interior that feels more 'premium' than many other mid-size crossovers; but its interior space is limited by its more curvaceous design.
You'll find the front seats in the Murano to be comfortable and adjustable for a wide range of sizes, although the sunroof does cut into headroom, and you need to think of the Murano as primarily a four-person vehicle. The rear bench feels a bit too low for adults, yet oddly, some adults might find headroom tight back there.
That shortage of seating space, and the surprising lack of cargo space behind the second row, are both results of the curvaceous exterior. Compare the seating (and especially the cargo space) in the Murano with that of boxy, upright vehicles like the Honda Pilot or the (outgoing) Ford Escape, then take a step back, and it's obvious that curves come at a price. The second-row seatback folds forward to expand cargo space, but it's hardly a box-like area and the cargo floor is quite high.
In keeping with the more premium feel of this model, the seatback is even power-operated on top models, and you can opt for a power liftgate; but unless you're having trouble reaching that high, it really isn't necessary here.
Interior appointments are very good overall—on par with the Maxima sedan and in some respects as good as a luxury-brand model. Trims and materials have a good look and feel, as does the switchgear, and riad abd wind noise are well isolated.
