Chicco MyFit Harness + Booster Car Seat

2-in-1 Comfort & Security

The Chicco MyFit harness/belt-positioning car seat is designed to grow with children from toddler through big kid with easy transition from five-point harness to vehicle seat belt. Nine headrest positions accommodate growth throughout both modes and work together with a four-position recline to support proper posture. An extra-deep ErgoBoost seat with dual-density foam padding is sloped and contoured for superior comfort.

Reassuring Protection

DuoGuard side-impact protection offers two layers of protection for two zones with a rigid shell and EPS energy-absorbing foam that surround the head and torso. The seat shell is also reinforced with a steel frame for superior impact protection.

Easiest to Install

From the makers of the #1-rated KeyFit and NextFit, the MyFit is designed with smart functionality that makes it the easiest to install simply, accurately, and securely, every time. A four-position ReclineSure leveling system and RideRight bubble levels help achieve and verify proper angle in the vehicle seat. Premium LATCH connectors and a LockSure belt-tightening system with wide routing make it easy to achieve a tight and secure fit with LATCH or the vehicle seat belt.

User-Friendly Touchpoints 

A padded, no-rethread harness with a one-pull tightener provides reassuring security for growing toddlers. The harness easily hides away to create a belt-positioning booster with shoulder and lap belt guides for big kids four years and up. Two dishwasher-safe CupFolders feature easy push-button removal and fold out of the way to save space when empty.
