Details
Why We Love It: The 2nd Seat Kit allows you to expand your stroller as your family grows. With plenty of different arrangements to accommodate children of all ages (infants, toddlers, and everyone in between), the whole family will be comfortable as you stroll around together. Also, the setup couldn't be easier — snapping on the Kit's adapters and 2nd seat takes less than 30 seconds.
What's Included: The 2nd Seat Kit comes with a Seat, Upper Adapters (to raise your 1st Seat and make room for the 2nd), Lower Adapters (to attach the 2nd Seat), Canopy, and attachable full-coverage Sunshade. For infant compatibility, you'll want to pair your 2nd Seat Kit with a Bassinet, Infant Seat Insert, and/or Car Seat Adapter (and for twins, we recommend using the 2nd Seat Kit with two Infant Seat Inserts).
Size & Weight Limits: Unlike some other two-seat strollers, our top and bottom seats are exactly the same. So you can use both of them with children up to 45 lb. The max headroom from the seat to the canopy is about 20".
Compatibility: This 2nd Seat Kit model is compatible with the Mockingbird Single-to-Double Stroller (both the original and 2.0 versions), but cannot be used with the Mockingbird Single Stroller. If you're unsure about which model you have, feel free to contact our product specialists.

Ready to roll?
We believe that functional design and stylish looks can go hand in hand—and they shouldn’t cost a fortune, either. Discover why a Mockingbird Stroller is right for your growing family.
