Parents Love Diono

The seat has a narrow design as it does not require thick, plastic sidewalls. So it takes up less space in the back meaning that together with Honey Nut's infant carrier, we can still have a small third person (ie my sister!) sitting in the middle seat.

Sabrina @ The Mummy Stylist (Radian 5)

It's very comfortable, long lasting, easy to install and is also perfect for the longer than the average child. It's wide yes - takes up a bit more space on the seat that smaller seats - but to be fair - it's a booster that is def. going to take you through to 12 years old no issues. Its cushion is very comfortable - all 3 of my kids have tried the one we currently have and all 3 were very happy with it. They sleep well in it on long journeys.
