Consider Cost Along With Double Stroller Cost
We have a BOB Duallie and a Britax B-Agile 35. This is a must-have item if you want to convert your stroller into a travel system and use in baby's first few months. Consider the cost of an adapter along with the cost of a double stroller, since this part is only sold separately. BOB has adapters for most, if not all, major car seat brands (Graco, Chicco, Britax, etc).
