Can the base be installed with just the seatbelt?

Hi Steph, thank you for your enquiry, yes the base can be used with the 3 point belt system, I have added a link to the website so you can follow the instructions in the manual to install the base with the 3 point seat belt. Otherwise, if you take the seat to your local Baby On the Move Store one of our trained Car Seat Technicians will install it correctly for you. We hope this helps. ?https://www.babyonthemove.co.nz/hire_products/hire-car-seats/maxi-cosi-mico-ap-wicking. For further information on this or any of our other products available, if you follow the link https://www.babyonthemove.co.nz/store-locations/ this will take you to our online store finder.
