What you need

  • The WonderFold W2 wagon
  • The Chicco KeyFit 30 carrier (its car base stays in the car)
  • The WonderFold W2 wagon adapter for Chicco seats (model W2CSA-CHC)

Step by step

  1. Set the stroller wagon's brake and unbutton the wagon fabric on the side where the adapter goes.
  2. Put a mounting bracket on each side of the frame with the metal piece on the outside, lined up with each other.
  3. Close the clasps around the frame, screw them shut, then fold the fabric back over the brackets and button it.
  4. Assemble the car seat frame, then screw the car seat supports onto the adapter, matching the 'Face Forward' mark.
  5. Set the adapter on the brackets facing the direction you want, then lock it by putting the metal clip over the bracket and pushing the clamp in.
  6. For extra stability, strap the car seat to the wagon's bottom crossbar with the included strap and pull it tight.

Retold from WonderFold manual (PDF).

Don't

  • A single car seat adapter must go on the front half of the wagon.
  • If the two brackets are not lined up, the adapter will not mount properly.
Checking the car seat is locked in (illustration)

Last check: give the carrier handle a gentle tug. A seat that is fully latched does not lift off.
