I will show you the major differences between the Britax Frontier and the Graco Nautilus 3-in1-Car Seat.

• Difference number 1- The Britax Frontier is more expensive than the Graco Nautilus.
  
• Difference number 2 - It is much easier to adjust the shoulder strap with the Frontier.
  A simple squeeze to the lever will do the job nicely.
  The Graco needs to be rethreaded.
  This can cause a lot of inconvenience if you intend to use it for another child.

  Graco's padding are not as thick as Britax Frontier and I feel that the Graco would be uncomfortable for long trips.

  5 inch seat width for the child to move around.
