Chicco MyFit Harness + Booster Car Seat - Grows with Your Child

In this review of the Chicco MyFit harness + booster car seat, the bottom line is simple: it is for parents who want a single seat that safely carries a child from toddlerhood into the booster years without frequent replacement. The seat's ability to transform from a forward-facing 5-point harness to a belt-positioning booster, combined with a wide range of headrest positions and a recline feature, makes it a practical, long-lasting choice for everyday family use. Installation aids and solid construction are the primary reasons many families will choose this seat.

Key Features

• 2-in-1 design: Converts from a forward-facing 5-point harness to a belt-positioning booster to support a child from about 25 to 100 lbs.
• DuoGuard protection: Deep rigid shell plus EPS energy-absorbing foam provide layered side-impact protection for head and torso.
• Steel-reinforced frame: Adds structural integrity and impact resistance while keeping the shell relatively slim for easier vehicle fit.
• Easy installation: Premium LATCH connectors, LockSure belt-tightening system, RideRight bubble levels and ReclineSure leveling help ensure a secure, correct install.
• Comfort features: A 9-position headrest, 4-position recline and an extra-deep ErgoBoost seat with dual-density foam deliver comfort on longer rides.
• Space-saving cup holders: Two dishwasher-safe CupFolders fold away with push-button removal to save space when not in use.

Who It's For

The Chicco MyFit is aimed at parents who want a single, durable seat that adapts as their child grows, eliminating the need to buy multiple seats. It suits families who value easy installation aids and those who frequently switch the seat between vehicles thanks to its clear leveling indicators and secure LATCH connectors.

It is less ideal for those who need a lightweight travel-only booster or who prefer a backless booster as soon as the vehicle belt fits; families who want the absolute smallest footprint may also consider slimmer booster-only options.
