The Graco SlimFit3 LX 3-in-1 Car Seat in Katrina is the slimmest all-in-one seat in Graco’s lineup, designed to fit 3 across in most vehicles without sacrificing comfort or safety. Perfect for growing families, this car seat transitions from rear-facing harness (5–40 lb) to forward-facing harness (26.5–65 lb) to highback booster (40–100 lb), offering long-term value in a compact design. The 16.7-inch-wide frame includes thoughtful features like an integrated belt lock-off for easy seat belt installs, InRight™ LATCH for one-second attachment, breathable mesh panels, and a Rapid Remove cover that detaches in 60 seconds for quick cleanup. Designed for use from infancy through youth.
