  3. Fold the fabric back over the frame and fasten it.
  4. Screw the car seat supports onto the adapter.
  5. Set the adapter on the brackets, then lock it by putting the metal clip over the bracket and pushing the clamp in.
  6. For extra stability, lower the car seat handle and strap both sides of it to the wagon's bottom crossbar, then pull tight.

Don't

  • With two car seats, both must face sideways.

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