Chicco Fit360 Rotating Convertible Car Seat Base (Additional Base for Multiple Vehicles)

At a Glance

The Chicco Fit360 Rotating Convertible Car Seat Additional Base gives families a convenient way to use one Fit360 car seat in another vehicle. Because every Fit360 rotating convertible car seat already includes one base, this additional base is ideal for a second family car or a vehicle used by grandparents, caregivers, or other trusted drivers.

Once a compatible Fit360 base is correctly installed in each vehicle, the rotating seat can be transferred from one base to another without reinstalling the entire car seat each time. The LeverLock™ system, six recline positions, bubble level indicators, and Ready-to-Ride indicators help support a secure, correctly positioned setup.

Why Families Choose an Additional Fit360 Base

• Convenient for multiple vehicles: Keep a properly installed base in another car so the Fit360 seat can move with your child between vehicles.
• Compatible across the Fit360 family: Chicco identifies this base as compatible with all Fit360 rotating convertible car seat models, including the Fit360 SE and Fit360 Zip.
• LeverLock™ installation: The self-tensioning lock system uses an open, route, buckle, and close process to help achieve a tight vehicle-seat installation.
• Six recline positions: The ReclineSure™ leveling system provides six settings to help position the base correctly in a range of vehicle seats.
• Easy-to-read leveling: Two RideRight™ bubble indicators help confirm that the selected recline angle is appropriate.
• Clear connection confirmation: An audible click and red-to-green Ready-to-Ride indicators help confirm when the Fit360 seat is correctly attached to the base.
• Rear- and forward-facing support: The same base supports compatible Fit360 rear-facing and forward-facing configurations when installed and adjusted according to the current user guide.

Important Installation and Safety Information

The Fit360 seat and base form a two-part child-restraint system. The rotating seat cannot be secured in a vehicle or used for travel without being correctly attached to a compatible Fit360 base.

Install the base with either the vehicle seat belt or the lower LATCH anchors—never use both installation methods at the same time. Chicco recommends installation with the vehicle lap-and-shoulder belt and top tether when available. The top tether must be routed and secured as directed for both rear-facing and forward-facing use.

Lower-anchor weight limits apply. Chicco instructs families to discontinue lower-anchor installation above 30 lb in rear-facing mode or 35 lb in forward-facing mode and switch to an approved vehicle-seat-belt installation. Always follow the instructions and limits for your exact Fit360 model and vehicle.

Before every trip, confirm that the base does not move more than one inch at the belt path, the seat has clicked securely into place, and both Ready-to-Ride indicators are green.

Can I move the Fit360 seat between two installed bases?
Yes. With a compatible Fit360 base correctly installed in each vehicle, the seat can be removed from one base and attached to the other. Listen for the attachment click and confirm that the indicators on both sides have changed to green before travel.

Does the base work for rear-facing and forward-facing use?
Yes. The Fit360 base supports compatible rear-facing and forward-facing configurations. Follow the current Fit360 instructions when changing modes, selecting a recline position, or updating the installation method.

Can the base be installed with a vehicle seat belt or LATCH?
Yes. The base can be installed using the vehicle seat belt or the lower LATCH anchors. Do not use both methods at the same time. Lower-anchor child-weight limits apply, and Chicco recommends the lap-and-shoulder belt with the top tether when available.

Is the top tether used while the Fit360 is rear-facing?
Yes. The current Chicco Fit360 instructions direct caregivers to use the top tether during both rear-facing and forward-facing installation.

The seat produces an audible click when it connects to the base. Ready-to-Ride indicators on both sides change from red to green when the seat is correctly positioned for travel. Check both indicators before every ride.

Does the additional base rotate?
The base remains secured to the vehicle seat. The compatible Fit360 car seat rotates while attached to the base, allowing the seat to turn toward the vehicle door for loading and return to the correct rear-facing or forward-facing travel position.

Can the Fit360 car seat be used without its base?
No. The Fit360 seat must be correctly attached to a compatible Fit360 base whenever it is used in a vehicle.
