Checking the exact car-seat model name, not just the brand, is essential before choosing an adapter.\nWonderFold W4 Carseat Adapter-UPPAbaby: Listen for the click and pull or tug the seat upward and side to side; loose movement means the seat should be reseated.\nWonderFold Car Seat Adapter for Stroller Wagon: The maker advises checking the car-seat maker for product status or recall information and checking the car seat label because car seats expire.",
