Product Description
CYBEX Pallas B4 i-Size Car Seat
The CYBEX Pallas B4 i-Size Car Seat is designed to provide long-lasting safety, comfort and adaptability from approximately 15 months through to 12 years. Suitable for children from 76 cm to 150 cm, its 2-in-1 design uses an adjustable impact shield during the younger stage before converting into a high-back booster as your child grows.
The impact shield is designed to help reduce strain on the neck in a frontal collision while still allowing natural upper-body movement. Linear Side-impact Protection, an energy-absorbing shell, ISOFIX connectors and Top Tether add further reassurance, while the 12-position headrest, reclining backrest and adjustable ISOFIX settings help create a comfortable fit across different stages.
