Convertible car seats
Rear-facing for infancy, then forward-facing with a harness. The 'keep them rear-facing longest' workhorse — many parents' one big seat.
🛟 Fit is decided by your seat manual + your vehicle manual. This page lists published specs to help you shortlist — it is not installation or safety advice, and it does not confirm a seat fits a specific car. Confirm install with the manuals, NHTSA, or a free certified car-seat technician (CPST) check.
