TriMate™ All-in-One Convertible Car Seat

The Safety 1st TriMate™  All-in-One Convertible Car Seat keeps little ones secure and comfortable, from baby to big kid. With three modes of use—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")—the TriMate is ready for every phase of your child’s development.

The seat’s ultra-slim design—just 17” across without the cup holders—allows parents to fit three across the back seat without sacrificing comfort. Seat pad is machine-washable and dryer-safe. You’ll always get the best fit with the 3-position adjustable base, 1-hand-adjustable harness system, and 9-position headrest.
