See How Simple: Great design is key to accurate installation the first day and every day. The MESA i-SIZE Infant Car Seat is R129 compliant and intuitively designed to easily install, thanks to innovative features that remove the guesswork.

Smart Secure Systems: An electronic indicator panel that provides visual and audio confirmations that guarantees the MESA i-SIZE is installed correctly the first time and every time. The SMARTSECURE system includes a unique tension indicator, ensuring the base is properly positioned to the vehicle seat, significantly reducing misuse.

Ease of Installation: The single action ISOfix release system allows caregivers to easily and properly install the base, removing the guesswork.

Advanced Side Impact Protection: To ensure better head, neck and overall protection, MESA i-SIZE’s headrest utilizes the absorption and recovery properties of both memory and EPP foam to provide advanced side impact protection that’s always engaged.

Hideaway Canopy With UPF 25+: The extra-large integrated, extendable canopy provides more protection outside and conveniently tucks away when not in use.

Height-adjustable Headrest with Integrated Harness System: MESA i-SIZE adjustable headrest integrated with a unique no-rethread, three-point harness eliminates the need to take the system apart as baby grows, providing a perfect fit to keep your infant safe and secure.

Included Robust Infant Insert: The removable infant insert ensures proper positioning in the carrier and better airway management for babies less than 60 cm.

Ventilation System: Keep baby comfortably cool thanks to a built-in ventilation system. Perforated holes in the shell of the car seat, combined with breathable mesh and EPP foam with vented channels, create more comfortable airflow.
