Q. Swift or Ignis me se kiski seats jyada comfortable he for long rides, I've back pain issue.

Ignis is a tough 5 seater and will be comfortable only with 4 onboard. The new swift will be better seating 5,and buy the ignis for urban usage and Swift would be better otherwise.

Bosss driver and side pessenger seat is very comfortable in swift for long rides, but the seat is confortable only for 2 passengers

Both give average rear passenger comfort.not by measurements the ne swift is the better of two.
