The 2004-2008 Generation of F150's offered two different styles of seats. One had integrated seatbelts (Regular/Extended Cab), one one without (Crew Cab). These vehicles had three main interior options: Cloth, Vinyl, and Leather. Rare features included seat memory, and seat heaters. Rear seats were interchangeable between cab sizes, however Crew Cabs usually came with a folding arm rest for the rear seat.
