Veer is the only wagon system I could find a Britax car seat adaptor for. So, to start off with, I am relieved.This contraption is straightforward to install, but kind of feels like you are going to break it while clicking it on and off. There are green indicators to help you know that it is fully latched. Feels secure when the car seat is installed and when baby is in it. I can fit my toddler comfortably on the other side of the wagon and even have sun shade and the the tray/cup holder in while the car seat is installed. There is also room to store extra stuff under the car seat in the wagon, so you don’t necessarily need the storage basket when using this configuration.
