The car seat is the most important safety accessory for your child. Mandatory from birth, it must be chosen carefully according to the baby's age, weight, and size. TrioNest™ explains everything about standards, groups, and selection criteria.
🛡️ The i-Size standard (R129): the new safety standard
Since 2013, the i-Size standard (R129 regulation) has been progressively replacing the old ECE R44 standard. It offers better protection thanks to:
- Classification by height (in cm) rather than by weight
- Mandatory rear-facing travel until at least 15 months
- Stricter side-impact tests
- Mandatory ISOFIX compatibility
TrioNest™ tip: always opt for an i-Size certified seat for maximum safety.
👶 Car seat groups
- Group 0+ (0-13 kg / 0-12 months): infant carrier, always rear-facing.
- Group 1 (9-18 kg / 9 months-4 years): booster seat with harness.
- Group 2/3 (15-36 kg / 3-12 years): booster seat with or without backrest.
- Convertible seats: cover multiple groups, more economical.
