Quick answer
To convert your single Mockingbird stroller to a double, purchase the Single-to-Double Stroller Seat 2.0 and follow these installation steps. The process takes about 10 minutes and requires no tools.
What you need before you start
You'll need the Single-to-Double Stroller Seat 2.0 (sold separately). This seat replaces the original single stroller seat and adds a second seat for a second child. The seat is designed to work with the existing stroller frame; no additional adapters or tools are required.
Common mistakes to avoid
A frequent error is trying to install the second seat without first removing the original seat. Ensure the stroller is in single mode before beginning. Another common issue is not fully engaging the seat into the frame's locking mechanism; listen for a distinct click on both sides.
Step-by-step installation
- 1. Remove the original single stroller seat: Press the release buttons on each side of the seat where it attaches to the frame. Lift the seat off and set it aside. The stroller frame is now ready for the new seat. Make sure both release buttons are fully pressed before lifting to avoid damaging the frame.
- 2. Attach the Single-to-Double Stroller Seat 2.0: Position the new seat onto the frame, aligning the connectors on each side. Press down firmly until you hear a click on both sides. Tug gently to confirm it's locked in place. If you don't hear a click, the seat is not fully secured. Check alignment and press again.
- 3. Adjust the harness for your child: The updated harness on the Seat 2.0 is easier to use. Pull the harness straps to the correct height for your child's shoulders and secure the buckle. Ensure the straps lie flat and are not twisted. Harness adjustment is critical for safety; always double-check that the straps are snug and the buckle is locked.
- 4. Test the double stroller configuration: With both seats installed, push the stroller to check for stability and smooth rolling. Make sure the second seat does not interfere with the front seat's recline or the folding mechanism. A quick test drive around the house reveals any issues before you head out.
