Car seats Group 0/1 (from 0 to 18 kg)

Group 0/1/ i-Size R129 car seats (40–105 cm / 0–4 years) combine the protection of an infant carrier with a longer usage period, so you do not have to change the seat right after the first year. In this category you will find rotating and fixed i-Size models that allow extended rear-facing travel and later forward-facing use according to the manufacturer’s recommendations.

The range includes car seats covering 40–105 cm, often with 360° rotation for easier access, multiple recline positions for sleeping, adjustable headrests and integrated newborn inserts. Some models are installed on an ISOFIX base with a support leg, others offer a belt installation option, and most feature enhanced side-impact protection, ventilation channels and comfortable fabrics suitable for everyday use.

At MagicOne you can choose Group 0/1/ i-Size seats from brands such as Avionaut, Caretero, Chipolino, Cosatto, Kinderkraft, Lorelli Premium, Moni and others, with different designs, comfort levels and extra features. There are more compact seats suitable for smaller cars, models with richer padding and soft zones, as well as solutions that cover a wider height range and can be used for a longer time with the same seat.

Use the filters by brand, height group (40–105 cm), installation method (ISOFIX or belt), presence of a rotating mechanism and price range to find the best option for your car and travel habits. Consider how long you plan to keep your child rear-facing, whether you often move the seat between different vehicles and whether your car has ISOFIX points – this will help you decide between lighter combination models and heavier but more convenient rotating i-Size seats for long-term use.

Frequency Asked Questions (FAQs)

Who are Group 0/1/ i-Size R129 car seats (40–105 cm / 0–4 years) suitable for, and when does it make sense to choose them instead of a separate infant carrier and a next-stage seat?
Combined 0/1/ i-Size seats are ideal for parents who want a single solution from birth up to about 4 years and prefer not to change seats after the first year. They work best if you mainly keep the child in the car and do not carry the seat in your hand very often, since they are heavier than classic infant carriers but offer a longer usage period.
How long can I keep my child rear-facing in a Group 0/1/ i-Size seat and why is this important?
Most 0/1/ i-Size seats allow rear-facing use from 40 to 105 cm, roughly from birth up to around 4 years, depending on the model. The longer your child travels rear-facing, the better the crash forces are distributed in a frontal impact and the less stress is placed on the neck and spine, so it is recommended to keep this mode for as long as the approved height range allows.
What is the difference between a rotating and a fixed 0/1/ i-Size seat, and is it worth choosing a 360° rotating model?
Rotating seats can be turned towards the door when placing and buckling the child, which makes everyday use much easier, especially as the child gets heavier. Fixed models are usually lighter and more budget-friendly, but require more bending over the seat each time, so the choice depends on your budget, how often you travel and how important convenience is to you.
How can I check if a 0/1/ i-Size seat is suitable for my car – what should I look for regarding ISOFIX, support leg and recline angle?
First, check whether your car has ISOFIX anchor points on the seat where you plan to install the child seat and whether the floor allows safe placement of a support leg (no storage boxes or shapes that conflict with the base). It is also important to look at the compatibility list provided by the manufacturer and make sure that, at the maximum recline angle, the seat does not press improperly against the front seat and can still lock securely.
How should I clean and maintain a 0/1/ i-Size seat without compromising safety and materials?
Always follow the manufacturer’s care instructions – usually the fabrics can be removed and washed at low temperature on a gentle cycle, while plastic parts should be wiped with a damp cloth and mild detergent. After washing, make sure the covers are refitted correctly, check that the harness slots and any rotation or recline mechanisms operate smoothly, and avoid fabric softeners or strong chemicals that could damage the harness or materials.
