Cybes Base S Modular Isofix Car Seat Base - BlackOn offer

Meet the only car seat base you’ll ever need. Designed for busy families, the CYBEX Base S provides a flexible foundation for your child's car seat journey from birth up to approximately seven years.

Part of the CYBEX Platinum S-Line Modular System, the Base S is compatible with three different car seats: the Cloud S infant car seat, Sirona S and Anoris S Airbag. This gives parents the flexibility to choose between extended rear-facing travel with the Sirona S or forward-facing protection with the Anoris S Airbag as their child grows.

Smooth one-handed rotation makes everyday journeys easier, allowing compatible seats to turn towards the car door for simpler loading and unloading. ISOFIX installation, an adjustable load leg and integrated LED safety indicators help provide a secure and straightforward installation every time.

Built with durable materials and designed for long-term use, the Base S provides one trusted foundation for countless family journeys.

Features

• Freedom of Choice – One base, two directions and up to seven years of flexibility. Start with the Cloud S infant car seat before moving to either the Sirona S for extended rear-facing travel or the Anoris S Airbag for forward-facing protection with integrated full-body airbag technology.
• Three-Seat Compatibility – The Base S is compatible with the Cloud S, Sirona S and Anoris S Airbag, allowing you to continue using the same base as your child grows.
• One-Handed Rotation – Smooth single-hand rotation makes getting your child in and out of the car easier. The Base S provides 180° rotation with the Cloud S and Anoris S Airbag and full 360° rotation with the Sirona S.
• Easy On- and Off-Boarding – Compatible seats can be rotated towards the car door, reducing awkward lifting and making it easier to position your child and secure their harness correctly.
• LED Safety Indicators – The integrated safety assistant helps guide correct installation. LED indicators display the status of the ISOFIX connectors, load leg, impact shield and battery, allowing you to check the installation at a glance before starting your journey.
• Made to Last – Newborn to 7 Years – Designed to support your family from birth up to approximately seven years, the Base S allows you to switch between compatible seats as your child's needs change. Durable materials and smart engineering provide lasting strength for everyday family use.
• Easy ISOFIX Installation – ISOFIX connectors and a height-adjustable load leg create a rigid and stable connection with the vehicle. Colour-coded ISOFIX release buttons and clear installation indicators help make fitting the base quick and straightforward.
• Platinum S-Line Modular System – The modular design provides flexibility throughout your child's early years, allowing you to choose between rear-facing and forward-facing compatible car seats without replacing the base.
