Does this seat have any back adjustment?

Hi Nadia, Thank you for your enquiry. Both the Britax Parkway SGL Booster and the Recaro Milano Booster are not designed to “recline” in the way that a toddler seat/restraint is designed or required to for installation. For further information on these seats, comparison and installation, if you follow the link https://www.babyonthemove.co.nz/store-locations/ this will take you to our online store finder. Here you can find contact details for your nearest Baby On The Move Store where one of our team experts will be happy to assist you in your product search and help answer any further questions you may have. We hope this has helped with your query.
