The Compass I420 Infant Car Seat is portable and full of top rated safety features. It is designed to fit the Inglesina Zippy Stroller with an easy to use mechanical attachment. This infant car seat is designed with a unique shell design that allows it to fit bigger babies but remains the same size as other infant seats on the outside. It has a full EPS (bicycle helmet foam) foam liner throughout the entire shell that absorbs energy to reduce the effects of a crash on the infant. The I420 has the deepest side wings of any infant seat to help contain the child in the event of a crash and uses two separately attached LATCH points. This reduces lateral movement of the seat in the event of a side impact collision. Provide your baby with a safe and comfortable ride while traveling. Important note: This infant car seat can not be used without the base.
