The Turn and Go 360 ST Rotating All-in-One Convertible Car Seat is designed with our innovative SafetySwivel 360° rotational technology, which lets you turn the car seat toward you, bringing you face-to-face with your little one. This rotation makes buckling and transferring your child in and out of the seat easier than ever and puts less strain on your back. Turn and Go 360 fits children from birth to 10 years in 3 modes: 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"). Our all-in-one car seat solves the number one installation problem that 7 out of 10 parents unknowingly have—loose belt tension. Turn and Go 360 ST features SecureTech, Safety 1st’s red-to-green indicators on the seat’s base that allow you to see when your belt has tension. Installation of the base is the same for all 3 modes of use, alleviating the need to re-install the base as your child grows. Whether you’re bringing home your new arrival or taking your big kid to school, you’ll travel in confidence through all their stages. The Turn and Go 360 ST meets or exceeds all federal safety standards and is National Highway Traffic Safety Administration (NHTSA) compliant. The attached connection cord ensures that the base and seat must be used together when installed. Actual fit may vary. Not all children will comfortably fit in the seat for the full weight and height ranges listed.
