A lightweight and safe booster seat for children 125–150 cm tall ensures correct seat belt routing and comfort on every trip. Thanks to ISOFIX it stays firmly in place on the seat, features a breathable cover, practical armrests, and a guiding clip for the ideal belt position. Approved to ECE R129 (i-Size).
Stable attachment with ISOFIX
Integrated ISOFIX connectors provide a firm, quick installation that prevents the booster from shifting and increases safety during braking.
Correct seat belt routing
The practical guiding clip helps position the belt so it runs correctly over the child’s shoulder and chest — not across the neck or under the arm.
Breathable and comfortable seating
The seat with breathable mesh fabric and soft padding provides comfort even on long journeys, complemented by padded armrests.
The PETITE&MARS Optimus Pro i-Size Grey Air booster is a reliable solution for older children who already use the vehicle’s three-point seat belt. Thanks to the sturdy ISOFIX anchorage made of stainless steel, it remains stable even during sudden braking and helps set the seating height for safe belt routing.
The breathable seating surface made of mesh material increases airflow and, together with soft padding and armrests, provides comfort even on longer trips. The removable and machine-washable cover makes maintenance easy, and the low weight simplifies moving it from car to car.
