Chicco KeyFit 35 Infant Car Seat and Base - Easy Install, Rear-Facing

In this review of the Chicco KeyFit 35 Infant Car Seat and Base, the bottom line is simple: this is an infant car seat designed for caregivers who want a secure, easy-to-install rear-facing seat that grows with baby. The KeyFit 35 stands out for its installation system and user-focused details, making it a reliable choice for parents who prioritize safety and straightforward setup. It is particularly strong for families who travel with a stroller system and value a seat that clicks into a base and compatible strollers without fuss.

Key Features

• Easy installation: Two bubble level-indicators and a spring-loaded leveling foot help achieve the proper base angle quickly and accurately for a secure fit in most vehicles.
• Adjustable headrest: The Easy-Extend Headrest System raises with the harness to accommodate growth up to 32 in and maintain correct positioning without rethreading the harness.
• Enhanced stability: An integrated anti-rebound bar increases stability in the vehicle and creates more leg room for extended rear-facing use.
• Strong LATCH system: SuperCinch force-multiplying LATCH tightener and a premium LATCH connector help achieve a snug, reliable attachment to the vehicle.
• Newborn support: The removable infant head and body support insert creates a proper newborn seating position and can be removed as baby grows.
• Travel friendly: The carrier clicks into the stay-in-car base and compatible Chicco strollers with a one-hand release for easy transfers during travel.

Who It's For

The KeyFit 35 is ideal for parents and caregivers of newborns and small infants up to 35 lbs who want a rear-facing car seat that is simple to install correctly and that integrates with a stroller system. It works well for those who value solid construction and a product that is ready out of the box and installs in minutes.

Families who need a lightweight carrier for very long walks or a convertible seat for extended forward-facing use should consider alternatives, since this is an infant-only rear-facing seat meant to be used with its base or compatible strollers and is best suited for infants within the specified size limits.

Pros & Cons

Pros

• Installation features like level indicators and a spring-loaded foot make getting a correct angle fast and repeatable.
• Easy-Extend Headrest System and no-rethread harness let the seat grow with the baby up to 32 in tall.
• Removable infant head and body support provides a secure newborn position out of the box.
• Compatible with Chicco strollers and includes a one-hand release for convenient travel.

Cons

• As an infant-only rear-facing seat, it will eventually need to be replaced by a convertible seat as the child outgrows the limits.
