it is the seat bottom and the back. the back looks easy to replace but the bottom may be different. the covers are just covers and can be taken off, getting them back on could be difficult. its bs that this happens and they don't do anything about it. nissan has lost a customer in my forever. i own an 05 altima and the 06 titan, never again will i buy anything they make.
from that ilustration it looks like #17 is the pad for the bottom of the seat?
a memeber on here offered me 2 08 seats for $225 for the pair but the color doesn't match. i was also thinking of getting some seat covers and adding some foam under them. i'm not sure what to do to be honest. i wish someone would just steal the damn thing and end this saga.
