The Kia Carnival's cabin is very spacious. The standard configuration is 7 seats (2+2+3 layout) with two independent captain's chairs in the second row for a more luxurious feel. The Premium variant can be upgraded to 8 seats (2+3+3 layout), replacing the second row with a bench seat for carrying more passengers. The 7-seat version offers easy access to the third row via the centre aisle; the 8-seat version carries one more person. The choice depends on your usage habits.
