According to the 2012 Toyota Brochure Information, the seats on the SR5, Off-Road, and Sport are defined as;
Sport fabric-trimmed front seats; 4-way adjustable driverís seat with power lumbar support; 4-way adjustable front passenger seat (with fold-flat capability on Double Cab)
The differences are;
A. SR5 fabric-trimmed seating surfaces (SR5), or;
B. Sport Water-Resistant Seats-trimmed front seats (Off Road - Sport)
A. Are the Front Seat Structure/Frame the same in the SR5, Off-Road, and Sport with the only difference being the Fabric Trim?
B. Are the Rear Seats in all (SR5, Off-Road, Sport) the same Structure/Frame and Fabric?
I have read many posts here about the seats but everyone has a bias toward their own so I have been unable to deduct the facts about the seats.
Any help is appreciated.
