Andrew T. –
daughter finds it comftable enough to sleep in and sit in on long journeys. Adjusts a lot more than previous car seats i have used, only one annoyance is the seat belt can be tight to press in with how wide the seat is…. in ford kuga its tight to clip in belt but in ford edge its not a issue, I imagine in smaller cars it may be a issue.
Kerys Taylor –
My daughter if of a very slim build but tall and this car seat is perfect for her shape. Looks good and is easy to fit.
