BOB Duallie Infant Car Seat Adapter with Tray
by Heather
Easy to assemble, and comes with a snack tray for the older sibling. and a second tray to add on if you decide to keep the bar attached once you are done using the car seat with the stroller. Will only work with one car seat at a time (can not fit two car seats on one stroller).
I feel as though my newborn and his car seat are extremely secure in the stroller. The only negative thing is that it makes the stroller harder to fold with the adapter bar installed, and therefore doesn't fully close (and won't fit into my car without taking the wheels off!)
Also, the BOB weather shield can not be used while the car seat adapter is in use.
