Cybex Car Seat Bases

Cybex Car Seat Bases

Make every journey easier with a Cybex ISOFIX car seat base. The Base T, Base S, Base G and Base G3 click securely into your car and let you swivel the seat towards the door, and each base works with more than one Cybex car seat as your child grows.

A Cybex ISOFIX base stays fitted in your car so you can click your child’s car seat on and off in seconds. Every base installs with ISOFIX and a height-adjustable load leg for a secure, stable fit, and each one rotates so you can turn the seat towards the car door for easy on and off-boarding.

Each base is part of a Cybex modular system, so one base can take your child from their infant seat to their next car seat:

  • Cybex Base T: part of the T-Line Modular System. It rotates 180° with the Cloud T and a full 360° with the Sirona T, and is approved under UN R129/03 i-Size.
  • Cybex Base S: the base for the Platinum S-Line. It works with the Cloud S (180°), Sirona S (360°) and Anoris S Airbag (180°), and has LED indicators that confirm correct installation.
  • Cybex Base G: designed exclusively for the Cloud G and Sirona G. Driving Direction Control keeps the Cloud G rear-facing.
  • Cybex Base G3: approved to UN R129/04 and compatible with the Cloud G3, Sirona G3, Cloud G and Sirona G, with rotation and one-click release.
