Avionaut MaxSpace AirFlow High Back Booster Car Seat - Navy

Avionaut MaxSpace Airflow High Back Booster Car Seat

The Avionaut MaxSpace Airflow High Back Booster is designed to deliver exceptional comfort, advanced safety, and outstanding ventilation for growing children. Suitable from 100–150cm (approximately 3 to 12 years or 15–50kg), this forward-facing booster seat builds on Avionaut’s award-winning MaxSpace design, now enhanced with breathable Airflow fabrics to keep your child cool and supported on every journey.

Certified to the latest R129/03 safety standard and positively ADAC tested, the MaxSpace Airflow features advanced side impact protection and intelligent ergonomic design to support healthy posture and spinal development throughout childhood.

Comfort & Ergonomic Support

The MaxSpace Comfort System+ has been carefully engineered to provide deep, profiled seating with additional cushioning that naturally contours the pelvis and reduces pressure on the lower coccyx. A profiled backrest ensures correct body positioning, while shaped cushioning in the cervical and lumbar areas supports spinal stability and helps relieve muscle tension and back fatigue.

Acknowledged and accredited by AGR (German Association for Healthy Back), this seat is ideal for long journeys and everyday travel alike.

Advanced Airflow & Spacious Design

Featuring innovative airy-mesh breathable covers, the MaxSpace Airflow promotes healthy airflow through the centre seat, backrest, and neck area. This enhanced ventilation helps regulate temperature and keeps your child cool and comfortable year-round.

With a generous 44cm seat width and a reclining backrest with resting mode, it is one of the widest high back boosters in its class and among the few to offer a tilt function for added comfort.

Intelligent Adjustability & Safety

The headrest offers one of the most extensive height adjustment ranges on the market and includes a unique headrest position indicator, allowing parents to accurately adjust both headrest and seatbelt height as their child grows.

The seat can be installed using either the vehicle seatbelt or Isofix connectors, with colour indicators to confirm correct installation and provide extra peace of mind.
