Details

What's Included: This set includes Upper Adapters (to raise your 1st Seat and make room for the 2nd) and Lower Adapters (to attach the 2nd Seat). These Adapters are included in the 2nd Seat Kit and do not need to be purchased separately unless you need a replacement pair. 

If you purchased a 2nd Seat Kit prior to April 2021, your Adapters may look a little different—we changed the design to make additional arrangements possible. Check out all the possibilities here.  

A note on purchasing 2nd Seat Kit Adapters instead of the full 2nd Seat Kit: Some families with a significant age or size gap between kids (~3+ years) may choose to purchase only the Adapters (Example: To use a Bassinet in the top positions and the Stroller’s included stroller seat in the bottom position). That said, if you ever plan to stroll with two stroller seats, we strongly recommend purchasing the 2nd Seat Kit, rather than purchasing the Adapters alone.
 

Compatibility: Please make sure you have the Single-to-Double Stroller model before purchasing these Adapters, as they are not compatible with the Single Stroller model. If you're unsure about which model you have, check out this Help Center article or feel free to contact our Mockingbird Product Specialists.
