Avis stocks a range of quality baby, infant and child seats to fit the younger members of your family. Simply request the seats you need at the time of booking.
UK law demands that anyone under 12 years' old, or under 135cm in height (approx. 4ft 5ins), must use an appropriate child restraint.
Visit GOV.UK for more details on child seat laws in the UK.
Reserve a seat online during the online reservation process. Once you've selected your vehicle group and cover option, you'll be asked to "Choose your Extras". Scroll down to the "Child seats" box and add one or more to your booking. Alternatively, request one via our reservations hotline or add one to an existing booking by calling Avis direct.
