    ISOFIX or Seatbelt

    ISOFIX and seat belts are two vital elements when it comes to children's car seats. Both keep the car seat secure.

    In terms of safety during impact, there is no difference between ISOFIX and belt attachment, as long as they are both installed correctly - they are as safe as each other.

    Weight limit or height limit first?

    Car seats that have a weight limit and a height limit are outgrown as soon as your child meets one of those limits. e.g. an infant carrier might have a 13kg weight limit and an 86cm height limit, the seat would be outgrown as soon as the child was 86cm even if they were only 11kg.

    What is the Swedish Plus Test?

    The Swedish Plus Test is the toughest crash test in the world! The Plus Test is a voluntary additional crash test that car seat manufacturers can apply for. Plus tested car seats ensure that your child is not exposed to life-threatening neck forces during a collision. Find out more about the Swedish Plus Test here.

    Can you help me install the car seat?

    Every car seat purchase includes either installation at Fakenham or remote support to ensure a safe install.
