Remove Existing Car Seat or Adapter
If a previous installation is in place, carefully detach the car seat or adapters following your stroller’s manual. Ensure the stroller is stable and on a flat surface.
Attach the Correct Car Seat Adapter
- Locate the adapter ports on your stroller. These are usually marked or color-coded.
- Align the adapters with your specific car seat model (e.g., Nuna PIPA or Cybex).
- Insert the adapters into the designated slots and secure them with a click or lock mechanism.
Secure the Car Seat to the Adapter
- Position the car seat onto the adapters, ensuring the connection points align correctly.
- Pull and press down gently to ensure the seat clicks into place. You should hear a click confirming secure attachment.
- Double-check by giving the seat a gentle tug—if it moves, repeat the attachment process.
Test the Installation and Adjust
Once attached, give the car seat a firm shake to verify stability. Make sure the harness or magnetic buckle is properly engaged and that the seat does not wobble.
Consult your stroller’s manual for specific safety checks and adjustment procedures.
