The Maxi-Cosi Pebble infant carrier is designed with deep sides for impact protection, and plenty of support in the contoured shape. It has a 3-point harness and an anti-misuse belt routing system which prevents the seat being fitted incorrectly with the car's seatbelt. The 3-point harness features an ingenious stay-open function which lets you place and secure baby in seconds. Both the harness and head support adjust together for better fit, comfort and safety. The Maxi-Cosi Pebble can be installed with 3 options: by using a FamilyFix base (Isofix) (sold separately); EasyBase 2 (sold separately), or with the car's standard 3-point seat belt. All our car seats and infant carriers comply with current European regulations ECE R44-03 or ECE R44.04.
