The Britax Frontier 90 car seat uses a brand new, almost fool-proof installation technology called the ClickTight Installation System. This technology allows parents to easily achieve a safe and secure installation using the vehicle seat belt throughout the life of the seat (in harness mode), without having to worry about the weight of the child. A car seat that is not installed tightly leaves children vulnerable to injury in the event of a crash. You can use this seat in harness mode up to 90 lbs., which is huge! The booster mode will take your child up to 120 lbs.
ALWAYS, make sure you refer to your car seat instruction manual, as well as your vehicle's owner's manual to find out how to correctly install your car seat.
