Life on the go just got easier with the Britax Infant Car Seat Adapter for Maxi Cosi, Cybex and Nuna. Whether you’re running a quick errand or embarking on a family road trip, you’ll enjoy the convenience of your own customized travel system. For use with B-Agile and B-Free strollers, Click & Go infant car seat adapters are included with the stroller. When using a Britax B-Agile or B-Free stroller, ensure the Click & Go Adapters are installed before attaching this adapter for select Cybex, Nuna or Maxi Cosi infant car seats. This item must be clicked into the adapters that came with the Britax B-Agile stroller. B-Ready strollers do not include Click & Go infant car seat adapters, therefore, this item can be installed directly into the Click & Go Receivers on the stroller frame.
