When my oldest turned two, I started dreading the car seat math — how many more seats would we need to buy before she could just use a regular seat belt? The Chicco MyFit solved that problem. It covers children from 25 pounds all the way to 100 pounds across two modes (harness and belt-positioning booster), which for most kids means roughly age 2 through age 10. After using one for several years, I can say it handles both stages well, with the kind of build quality and safety credentials that justify the mid-range price. Check the latest price on Amazon.

Safety Performance
The Chicco MyFit earned an IIHS Best Bet rating as a booster seat, meaning it provides optimal seat belt positioning for children ages 4–8 across standard cars, SUVs, and minivans. That’s a meaningful endorsement — the IIHS testing evaluates real-world belt fit, not just crash performance.
The steel-reinforced frame and energy-absorbing base form a rigid structure that reduces force transfer during impacts. DuoGuard side-impact protection adds dedicated padding around the torso and head — the two areas most vulnerable in side collisions. The 5-point harness keeps younger children secured with the kind of restraint system safety experts prefer over seat belts for children under 65 pounds.
Chicco’s SuperCinch LATCH tightener deserves special mention. It uses a ratcheting mechanism that lets you get a tight, secure installation without the wrestling match that traditional LATCH connections sometimes require. The built-in bubble level indicator confirms you’ve got the correct recline angle, taking the guesswork out of installation.
The NHTSA gave the MyFit 5 out of 5 stars for installation features — one of the highest scores in its category.
Daily Use and Comfort
Nine recline positions is more than most harness-to-booster seats offer, and the range makes a real difference on long drives. A sleeping child whose head falls forward is uncomfortable and potentially unsafe — the ability to add a few degrees of recline helps the headrest do its job.
The ErgoBoost dual-layer foam padding provides genuine comfort without feeling bulky. The head area gets extra DuoGuard padding, which serves double duty as both comfort and safety. The seat fabric is breathable, and the cover removes easily for machine washing — a significant advantage over seats that require hand-washing.
Chicco’s “Cup Folder” cup holders attach to the seat base and can be removed entirely or folded flat against the sides when you need extra clearance for adjacent seats. It’s a thoughtful design that acknowledges the reality of multi-seat installations.
One note on harness adjustment: the MyFit does not have a no-rethread harness. You’ll need to rethread the harness straps when adjusting height, which requires removing the seat cover. The harness also needs rethreading after cleaning. This is the seat’s most notable convenience drawback.
Chicco MyFit vs Britax Grow With You ClickTight
| Feature | Chicco MyFit | Britax Grow With You |
|---|---|---|
| Harness Mode | 25–65 lbs, up to 54 in | 25–65 lbs, up to 58 in |
| Booster Mode | 40–100 lbs, up to 57 in | 40–120 lbs, up to 63 in |
| Installation | SuperCinch LATCH | ClickTight |
| Recline Positions | 9 | 2 |
| IIHS Rating | Best Bet | Best Bet |
| Width | 20.5 in | 20.5 in |
| Price Range | Lower | Higher (~$100 more) |
Both seats earn IIHS Best Bet status and share similar safety features (steel frame, dual-layer side-impact protection). The Britax accommodates taller and heavier children — up to 120 lbs and 63 inches in booster mode versus the MyFit’s 100 lbs and 57 inches. The ClickTight installation system is also faster for families who frequently move the seat between vehicles.
The Chicco wins on recline versatility (9 positions vs 2) and price (typically around $100 less). For families who install the seat once and leave it, the MyFit offers comparable safety at a better value. If you need the seat to last through larger, older children or swap vehicles often, the Britax Grow With You is worth the premium.
Pros and Cons
What We Like:
- IIHS Best Bet booster rating
- Steel-reinforced frame with DuoGuard side-impact protection
- 9 recline positions — more than most competitors
- SuperCinch LATCH makes installation tight and secure (NHTSA 5/5 for installation)
- Covers 25–100 lbs across harness and booster modes
- Machine-washable cover
- Removable/foldable cup holders for multi-seat flexibility
- FAA approved in harness mode
What Could Be Better:
- Harness requires rethreading to adjust height (no front-adjust system)
- 25 lbs is relatively heavy for portability
- Labels could be clearer — NHTSA rated labels just 2/5 stars
- Harness must be rethreaded after disassembly for cleaning
- 100-lb booster limit is lower than some competitors (Britax goes to 120 lbs)
Our Verdict
The Chicco MyFit hits a sweet spot in the harness-to-booster category: solid safety credentials (IIHS Best Bet, steel frame, DuoGuard protection), good comfort (9 recline positions, dual-layer foam), and a price that undercuts the premium competition by about $100. The SuperCinch LATCH system makes installation genuinely easy, and the machine-washable cover saves sanity.
The harness rethreading is a real inconvenience, but it’s a trade-off shared by many seats in this price range. For most families looking for a single seat to take their child from the harness stage through the end of the booster stage, the MyFit delivers excellent value. If your child is already on the larger side or you want the very easiest installation, consider the Britax Grow With You ClickTight instead. See all our top picks in the best-rated car seats guide.
