It’s one of those questions that we all ponder on from time to time, isn’t it? Why is it that a child can only use a regular car seat with a harness up to “18kg” (most commonly on ISOfix car seats) but she’s perfectly OK to go into a high back booster that also has “isofix”? ISOfix has a max weight of 33kg for child + car seat – surely that is still the case on a high back booster?
What is the difference between ISOFIX & ISOFIT question answered right here! #Britax #carseatsafety #isofix #isofit #knowhow #carseats Share on X
The answer is actually NO – that’s not the case on high back boosters.
Why? It’s very simple and it’s explained very well by Britax UK:
ISOFIX and ISOFIT are child safety seats that are attached to the vehicle body with connectors. With ISOFIX seats, the child is secured by means of a five point safety harness; with ISOFIT by means of the vehicle’s 3 point seat belt. An additional distinguishing feature is the classification of the child safety seat. The ISOFIX description is used for Group 0+ and 1, and the ISOFIT description for Group 2/3.
I hope the explanation was easy to understand and helped you.
Have a wonderful day! x
