Fans of the BOB Duallie stroller will love the extra flexibility this car seat adapter gives them. It lets you move your infant car seat, baby and all, from the car to the stroller and back again, so no nap needs ever be disturbed. It also includes two snack trays (one is pre-installed) that have space for sippy cups, snacks and toys. It's compatible with the BOB Duallie (although the Duallie can only accommodate one car seat at a time) and works with most popular infant car seats. See "Product
