The Safety 1st TriFit All-in-One Convertible Car Seat is built to grow with your child while keeping them safe and comfortable on the road. With three modes of use—rear-facing, front-facing, and belt-positioning booster—the Safety 1st TriFit is ready to take your baby home from the hospital or take your big kid to soccer practice. The seat’s ultra slim design allows for fitting three across the back seat without sacrificing safety or comfort. With a 3-position adjustable base, a 1-hand-adjustable headrest and harness system, and machine washable and dryable fabric, it’s the only car seat your child will need. Fits kids from birth through age 10 in three modes: rear-facing (5–40 lbs. and 19”–40”), forward-facing (30–65 lbs. and 34.4”–49”), and belt-positioning booster (40-100 lbs. and 43.4”–52”).
