  "answer": "Mockingbird Single-to-Double Stroller Seat 2.0: The product is the Single-to-Double Stroller Seat 2.0 by Mockingbird, a replacement part. The Stroller Seat is compatible with all Mockingbird Single-to-Double Strollers and 2nd Seat Kits, including 2023 and earlier models; for a Single Stroller replacement, contact Mockingbird Product Specialists.\nMockingbird Replacement 2nd Seat Kit Adapters Set: Converting the stroller to a double is described as moving the first seat up with the upper adapters and then attaching the second seat with the lower adapters. The second seat kit does not fit the older single Mockingbird stroller: the bar holding the basket under the seat sits where the second seat adapter needs to clip on.",
