Is it normal for the Switchback Seat and Infant Car Seat to have movement when attached to the &Roll and &Jog?Updated 7 months ago

Yes!  

When you attach the Switchback Seat and/or Infant Car Seat to the &Roll and &Jog frames, you may notice some movement in the connection.  Some describe it as somewhat of a wobble.  This is intended because it facilitates a quicker, easier attachment of the Switchback Seat and/or Infant Car Seat to the frame and helps provide a smoother ride for the passenger.  Once the child is in the seat, the weight of the child dampens the movement.

Rest assured, the Switchback system meets or exceeds global compliance testing that specifically considers the connection of seats and frames. Every innovative detail on the Switchback Seat and Infant Car Seat Adapters has been carefully considered to balance performance, functionality and ride!
