The SlimFit's hallmark is its narrow profile, allowing it to fit three across in vehicles like the Honda Odyssey or Toyota Camry—real-world tested with 95% success in standard midsize cars. No more sacrificing safety for siblings.
Graco's ProtectPlus system provides enhanced protection in frontal, side, rear, and rollover crashes. Rear-facing crash scores hit 4.7/5, forward-facing 4.3/5, and booster mode 4.2/5. Steel-reinforced frame and energy-absorbing foam add peace of mind.
At 19.5 lbs, it's portable yet sturdy. The InRight LATCH system simplifies installs: rear-facing LATCH scores 4.2/5, forward-facing 3.8/5.
Harness fastens/unfastens in seconds (5/5 score), and booster conversion is a breeze (5/5). Vehicle adjustments are intuitive, though rethreading the harness for mode changes takes practice (3.5/5).
