Compared To

MyFit is forward-facing only and has a taller harness limit (54" vs 49"); NextFit can rear-face but has lower harness height.

vs Chicco OneFit

OneFit is all-in-one (rear-facing, forward, booster) but lower harness height than MyFit; MyFit is narrower and better suited for extended harnessing of older kids.

Source Threads

Chicco NextFit or MyFit? Clarifying differences for forward-facing
The NextFit is a convertible seat that can rear-face but has a forward harness limit of 49". The MyFit is a forward-only combination seat with a 54" harness limit, making it better for taller kids who have outgrown a convertible. If you need a harness to last for a child who is already tall, the MyFit is the better choice.

Preschooler's mom asks about next car seat after outgrowing infant seat
I'd recommend the Chicco MyFit if you want to keep harnessing. It has a 54" height limit in harness mode, which is one of the tallest. Perfect for tall preschoolers who aren't ready for a booster.

Chicco OneFit vs MyFit for three across and extended harnessing
The OneFit does everything, but its top harness height is lower than the MyFit. For a 3-across, the MyFit is slimmer (17.5" with cupholders folded), so it's often the better pick. If you want the tallest harness, go MyFit; if you need rear-facing, go OneFit, but know you'll lose harness height.

Understanding Chicco MyFit height limits and installation quirks
The 54" limit is standing height, but actual fit is determined by torso height — shoulders must be below top harness slot. The MyFit has about 19.5" top harness height. Installation can be tough in some cars. The lock-off is for seatbelt installs but doesn't aid tightening like Britax.

MyFit install dilemma: gap behind seat in Toyota Camry
I installed the MyFit in my 2013 Camry and there's a gap between the car seat and the vehicle seat. The fixed headrest is pushing it forward. Chicco generally wants the seat to sit flush, so check the manual. Some recommend trying Britax if the gap persists.
