How to Fit the Ergobaby Metro 3 Car Seat Adapter

Quick answer

Attach the adapters to the stroller frame, then click your compatible infant car seat onto the colored indicators. The whole process takes under a minute once you know the two common pitfalls.

Step-by-step fitting guide

1. 1. Locate the adapter attachment points: On each side of the Metro 3 stroller frame, find the small slots near the armrest. The adapter arms have a tab that slides into these slots. Common mistake: trying to attach the adapter to the fabric canopy or seat back—only the frame slots are correct.
2. 2. Slide and click the adapter into place: Hold the adapter with the color-coded indicators facing outward. Slide the tab into the frame slot until you hear a click. Repeat on the other side. Checkpoint: both adapters should sit flush against the frame and not wobble when you tug them gently.
3. 3. Align your car seat onto the adapters: Lower your infant car seat onto the adapters so the seat's built-in connectors meet the colored indicators. Press down firmly until you hear a second click. Common mistake: pressing only one side. Apply even pressure to both sides simultaneously to avoid a partial latch.
4. 4. Verify the connection is secure: Lift the car seat by the handle—it should stay locked to the stroller. Check that the release buttons on the adapters are not visible (they retract when locked). Empty
