Cybex Base G3 360° Rotating ISOFIX Car Seat Base

CYBEX Base G3 i-Size ISOFIX Car Seat Base - One Base, Two Seats

The CYBEX Base G3 i-Size is the ISOFIX base designed to work with the CYBEX G3 Modular System, offering a long-term solution that grows alongside your child from birth to approximately four years old. Compatible with the CYBEX Cloud G3 infant car seat and the CYBEX Sirona G3 toddler car seat - as well as the previous-generation Cloud G i-Size and Sirona G i-Size - the Base G3 is built around making every car journey simpler, safer, and less physically demanding for parents.

360° Rotation for Effortless On and Off-Boarding

The stand-out feature of the Base G3 is its rotation system. Rather than leaning into the car to buckle or position your child in a fixed seat, a single pull of the rotation handle swings the car seat towards the door. The seat releases from the base simultaneously, so you can lift your child straight out without twisting or stretching. The same smooth motion works in reverse when loading your child in - rotate the seat to face you, settle them in, and click it back onto the base. For parents doing this multiple times a day, the difference to back strain and general convenience is significant.

Driving Direction Control (D.D.C.)

The Base G3 features CYBEX's Driving Direction Control system - a built-in safety mechanism that prevents the Cloud G3 and Cloud G i-Size infant car seats from being attached in any position other than rear-facing. This removes any possibility of accidental misinstallation for the most vulnerable stage of travel. When your child moves on to the Sirona G3 or Sirona G i-Size toddler seat, the D.D.C. offers two further settings that allow you to choose between rear-facing and forward-facing use, giving you full flexibility as your child grows and your preferences evolve.

Simple, Secure ISOFIX Installation

The Base G3 installs in your vehicle using ISOFIX, with parent-friendly ISOFIX release buttons that make attaching and detaching the base straightforward. A height-adjustable load leg provides additional stability and can be set to suit the angle and depth of your vehicle's floor, ensuring a firm, consistent fit regardless of which car the base is installed in. Always check CYBEX's Car Compatibility Checker before purchase to confirm the base is approved for your specific vehicle.

One Base - Two Seats

Buying a new ISOFIX base each time you move up a seat stage is one of the hidden costs of the early years. The Base G3 is designed to eliminate that. A single purchase covers the Cloud G3 from birth to approximately 24 months, then transitions seamlessly to support the Sirona G3 from birth through to approximately four years old. If you're planning for a growing family - or a second child - the Base G3's compatibility with both the G3 and previous G i-Size generation seats adds further long-term value.
