"Standard" seats and comfort seats are completely different items. All 4.8is' came with sport seats or comfort seats (as a no cost option). On other models both were extra charge (unless sport pack equipped=sport seats). The comfort seats have more adjustments than either the sport or standard seats, though they don't have the large bolsters or leg extensions of the sport seats. I think they have an extra back adjustment where you can make the seatback like ) as opposed to /, \, or l. Both will feature lumbar support. I have never sat on comfort seats, but have not heard any complaints about them. I love the sport seats on mine, but I'm a shorty @ 6'2".
