iSize R129 Car seats explained
ECE R129 (i-Size) is the most recent safety Regulation controlling the manufacture of children’s car seat which was introduced in 2013. The intention was to make child car seats easier to fit, provide better protection from side impact and keep children rear facing for longer (this is considered the safest mode of transporting children).
ECE R129 (i-Size) car seats are the newest standard of car seat safety and force the industry to adhere to the highest of safety standards. ECE R44/04 is an older set of safety standards and it is being phased out by a new wave of ECE R129 (i-Size) car seats.

Difference between the two models
You choose the seat depending on your child's height, not weight. This can make things safer as most parents know the height of their child better than the weight. You'll find it easier to ensure your child is in the right size seat.
It is considered the safest standard with improved head and neck protection.
Side-impact crash test results are assessed as part of the standard.
You have to use ISOFIX, which attaches the car seat directly to your car’s chassis, with an i-Size car seat. ISOFIX car seats are more likely to be correctly fitted in your vehicle. Bare in mind that you need an additional ISOFIX base to install a baby car seat using ISOFIX.
