BeSafe Flex FIX 2

ColourFresh Black Cab

High-back booster seat upgraded from our award-winning favourite iZi Flex FIX i Size. This seat is used when the child is ready to sit front facing (from 4 years or older). It combines excellent safety, optimum comfort and quality design to accommodate up to three car seats in a row. For your child’s safety, we recommend that you wait as long as possible before turning them around to face forward. Discover our rear-facing car seats for children over 4 years.

  1. 3 car seats in a row 
    Make room for up to three children in a row by simply removing both SIP bars from the middle seat.
  2. PAD+
    Designed for extra chin and chest protection, PAD+ offers soft, comfortable padding against the edge of the seat belt.
  3. Belt guides 
    The innovative lap belt guide from BeSafe is based on our proven pregnancy belt technology. This intelligent solution prevents the child’s body from sliding forward and under the seat belt and always ensures correct positioning of the lap belt. With our shoulder belt guide, positioning your seat belt is now even easier and more precise. The lap belt guider is easily detachable making it possible to wash when needed.
  4. Recline position
    The seat can be easily adjusted in a reclined position, which provides added comfort and protects your child. When your child gets sleepy in the car, the reclined position helps ensure their head and torso stay protected inside the car seat.
  5. Innovative headrest
    Innovative headrest construction with a trampoline-like protection effect.

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.
