The Infasecure Transit booster seat is a functional and well-featured booster seat. On safety, while it does include the inbuilt Air Cocoon Technology side impact protection, it did score 3.7 stars on the latest CREP safety protection rating, which is a good score but is bettered by a few other booster seats.
It is very suitable for larger children with a wide internal base (43cm) and high upper height marker (52.5cm) which means you can use this seat for a lot longer. An adjustable headrest and arm rests which also work as the seat belt guide to protect from submarining are valuable features which distinguish it from lower priced seats.
There are a lot of other booster seats around the price but the Infasecure Transit is quite a capable one. Just hope you like black.
