For busy parents on the go, the All4Stages car seat allows you to seamlessly transfer between family cars or rentals for an easy, on-the-go solution. The streamlined 16.9 in. footprint saves space for other backseat passengers or allows you to fit three car seats across in your backseat. All4Stages Slim can be used for up to 10 years through four different modes: Rear-Facing (4 - 40 lb), Forward-Facing (30 - 65 lb), High-Back Booster (40 - 100 lb), and No-Back Booster (40 - 120 lb). The removable canopy helps shield your child from the sun while rear-facing in the vehicle. Achieve a secure installation with up to 50% less effort with SecureTight™. The 12-position headrest and no-rethread harness both adjust with one hand. There are four rear-facing recline options and two forward-facing recline options for optimal positioning and improved vehicle fit. Removeable cupholders and a snack tray provide easy, portable snacking.
