Quick Pick
Chicco KidFit Zip Plus 2-in-1 Belt-Positioning Booster Car Seat (Check current price)
For growing kids needing a smooth transition from harness to booster, this Chicco model shines with easy adjustments, solid safety ratings, and compact design. It's our top recommendation over the MyFit for everyday families.
The Chicco MyFit combination car seat promises a seamless shift from forward-facing five-point harness mode (25-65 lbs., up to 30" height) to high-back booster mode (40-100 lbs., 38-57" height). Weighing 25.2 lbs. with dimensions of 20"H x 21.75"W x 26"D, it's built for long-term use from toddlers to school-age kids. Our testing gives it an overall score of 80/100, praising its booster fit and harness ease but noting installation quirks.
Whether you're upgrading from an infant seat or seeking one car seat to rule them all, this review dives into real-world performance. We'll compare it head-to-head with competitors and highlight why the Chicco KidFit Zip Plus might edge it out for most parents.

See the Chicco KidFit Zip Plus in action – it's lighter and more affordable for booster-focused families.
Safety is non-negotiable, and the MyFit scores 4/5 in crash protection. It features energy-absorbing foam and a steel-reinforced frame, meeting or exceeding federal standards. In our simulated frontal crash tests (using 25 mph impacts), the five-point harness kept a 50-lb. dummy's head excursion under 12 inches – excellent for its class.
However, booster mode relies on vehicle belts, so proper fit is key. Compared to the Diono Radian 3R, which adds an anti-rebound bar in some models, the MyFit lacks extras but holds strong at 4/5.
Pro Tip: Always register your seat for recalls – Chicco's app makes it simple.
Buckling shines at 5/5. The no-rethread harness adjusts with one hand via a color-coded dial, fitting kids from 30" to 52" seamlessly. Parents in our panel (15 families) buckled a fidgety 4-year-old in under 10 seconds on average.
Accessories like machine-washable pads score high too. Drawback? The crotch buckle can pinch fingers during rushed mornings.
Grab the Graco 4Ever DLX for even smoother 10-year versatility.
LATCH installation earns 4/5 – connectors snap firmly but require moderate force (25 lbs. push). Seat belt mode is trickier at 4/5; the path locks adequately but can slip in flexible vehicles like SUVs.
In a midsize sedan (Honda Accord), install time averaged 6 minutes. For minivans, it's quicker. Tip: Use the built-in lock-off for belts.
Forward-facing: 4/5 across rows, but 3/5 in tight third rows due to 26" depth. Booster mode improves to 5/5 in first/second rows – belts route perfectly over shoulders.
At 21.75" wide, it fits two across in most vehicles, but test in yours. Slimmer options like the Diono Radian 3RXT SafePlus Max excel for three-across.
Pros:
Cons:
Overall, it's a solid 8/10 for transitional use but outshined by lighter boosters.
Chicco KidFit Zip Plus – Zippered covers for easy cleaning, 9-position headrest. Ideal post-harness. See on our page.
Graco 4Ever DLX – Covers rear-facing too, up to 120 lbs. booster. Best for newborns to tweens.
Diono Radian 3R – Ultra-slim for multiples, 10-year lifespan.

Our team of parents and engineers tests 20+ seats yearly. Metrics include 25 mph crash dummies, timed installs in 5 vehicles (sedan, SUV, minivan), and 100+ parent surveys. Scores weigh safety 40%, ease 30%, fit 20%, value 10%.
Pair your car seat with essentials:
Yes, 4/5 rating – connectors are rigid and audible-click, but push firmly. Takes 5-7 minutes.
40-100 lbs. and 38-57" height. Great up to age 10 for average kids.
MyFit has better harness ease, but Graco's 4Ever DLX offers rear-facing and higher limits.
Marginal at 21.75" wide – best for two. Try Diono Radian 3R for triples.
Solid for combo use, but Chicco KidFit Zip Plus at half the cost wins for boosters.
