The Alpha Omega Elite 65 Convertible Car Seat by Safety 1st is an extended-use car seat with superior comfort and convenience features. It keeps your growing child safer while riding in the car, from a tiny baby coming home from the hospital to an older child going to school. It starts as a rear-facing infant car seat with a removable infant support to keep smaller babies snugly positioned. It then converts to a forward-facing harnessed car seat and later transitions into a belt-positioning booster for use up to 100 pounds. Padded harness covers, infant head support and toddler pillow keep baby comfortable for the journey ahead. The moveable armrests make it easier to get in and out of the seat, and the QuickFit™ harness adjusts with the headrest easily without uninstalling the harness, or removing the seat from the car!
