Size and installation

Hi Georgia
Thank you for your inquiry. Yes, it can be installed with a seat belt only. The Boulevard is one of our compact seats for rear facing, however, we would advise if you can bring your car to your nearest Baby On The Move store then we can check it fits your vehicle correctly. If you do have bad bucket seats, we can pack it out with a towel or purchase a Sit Rite -https://www.babyonthemove.co.nz/car-seat/restraint-accessories/Diono-Sit-Rite which helps get a proper angle for rear facing. We hope that helps.
