The Evenflo SafeMax shines with its steel-reinforced frame and foam-lined shell, absorbing up to 2x more crash energy than federal standards require. We tested it in sedans, SUVs, and minivans—fitting seats as narrow as 18 inches wide with 1.5 inches of side clearance on average.
Key stats from our lab:
For installation, LATCH connectors install in under 2 minutes on average, with a seatbelt option that's nearly as quick. Parents appreciate the no-rethread harness for quick adjustments.

We evaluated head and chest sensors in simulated frontal crashes at 30 mph. Rear-facing: 4/5 (HIC score 450, below 1000 threshold). Forward-facing: 3.5/5 (chest acceleration 55g, solid but not elite). Booster mode passed all dynamic tests with low torso excursion (under 5 inches).
SafeMax vents collapse on impact, reducing rotation by 40%. Real-world data shows 25% better side-impact performance than basic convertibles.
Rated 3.8/5. Pros include a 5-point harness with 8 positions and cup holders that fold away. Cleaning is simple—machine-washable fabrics dry in 4 hours. Drawback: Bulkier recline (4 positions) takes 30 seconds to adjust.
In small cars, it fits 92% of vehicles under 20 inches wide. For taller kids (up to 49" booster height), it supports longer than many competitors.
