The Baby Trend Trooper Slim 3-in-1 Convertible Car Seat converts from rear-facing infant seat and rear-facing toddler seat to forward-facing toddler seat as your child grows. This latest version of the Trooper has been tested to the new Fmvss 213a Side Impact Safety Standards. With 5-position shoulder height adjustment and 2-position crotch buckle for seat adjustment, the Trooper Convertible gives parents the ultra-convenience for installation and adjustment. The rear-facing recline flip foot allows the Trooper to get great installation angles with ease.
