The Rocker Base is part of Orbit Baby’s revolutionary SmartHub system: dock and rotate any Orbit Baby seat onto the Rocker Base to form a rocking seat. Dock your Bassinet to form a modern cradle at bedside height, or your Stroller Seat to form a reclinable rocking seat with integrated snack tray and footrest. Orbit Baby infant or toddler car seats can also dock onto the Rocker Base to transition a sleeping child from your car or stroller.
