The Evenflo Pivot Xpand Stroller Adapter Accessory allows your stroller to grow with your family by making your single stroller a double stroller. This adapter is designed to upgrade your stroller to fit two infant car seats or one infant and one toddler car seat. Slide the top location up and install the adapter so your baby is closest to you. The adapter fits in either the top or bottom location and can be placed either forward-facing or parent-facing. This car seat adapter was designed exclusively for the Chicco KeyFit 30, Graco SnugRide Click Connect 30, 35, Graco SugRide SnugLock 30,35 Peg Perego Primo Viaggio as well as select Evenflo strollers.
