We understand that your child's safety is a top priority for you. That's why we've put together detailed information to help you choose the best car seat group 1/2/3 for your child weighing between 9 and 36 kg and measuring up to 150 cm. In this article, we'll look at the most important features to consider when buying a car seat for your child, as well as the top-rated models on the market.
What is a Group 1 2 3 car seat?
A Group 1/2/3 upgradeable car seat is a practical option for parents looking to buy a single seat for their child, which can be used as their child grows. These seats offer increased safety and durability, particularly compared with child car seats that are intended to be used for a shorter lifespan.
Regulations for convertible car seats
Regulation R44/04 classifies car seats into groups according to the child's weight. For group 1/2/3 car seats, the weight limit is between 9 and 36 kg, corresponding to an age range from around 9 months to 12 years. This classification is important to help parents choose a car seat that suits their child's morphology and to ensure that he or she is properly supported and protected in the event of an accident.
R129 (i-Size) regulations
The i-Size regulation (R129) aims to provide better protection for children in the event of a road accident by classifying car seats according to the size of the child. It is more recent and stricter in terms of safety than the R44/04 regulation, as it takes into account additional safety criteria such as side impact tests and the compulsory use of rear-facing car seats for children under 15 months of age. For group 1/2/3, the i-Size equivalent corresponds to children measuring between 76 cm and 150 cm, i.e. from around 15 months to 12 years of age.
The advantages of Group 1 2 3 car seats
Group 1/2/3 car seats are evolutionary seats designed to accompany the child's growth and offer maximum protection during car journeys. By moving from one group to another, these seats offer a practical and economical solution for parents, while guaranteeing their child's safety.
One of the advantages of Group 1 2 3 car seats is that they are economical, as they can be used for several years. In fact, by using a car seat of this type, you won't need to change it every time your child grows up, which can mean significant savings for parents in the long term. So it's a wise investment for anyone looking to protect their child on a budget.
As well as being economical, Group 1 2 3 car seats also offer great versatility. They can be used for different ages and sizes of child, making them very practical for families with several children or for those looking to invest in a car seat that will last for many years.
Precautions to take with Group 1 2 3 car seats
When choosing a Group 1/2/3 car seat, it is essential to pay particular attention to safety features. Evolving car seats, which can be used for different weight and height categories, are not always as safe as traditional models, as they must be able to adapt to body shapes ranging from 9 to 36 kg (R44/04 regulations) or 76 to 150 cm (R129 regulations).
Although 1/2/3 progressive car seats have been extensively tested, the list of the best performing models is still fairly limited. Given that these seats are designed exclusively to be forward-facing, this can represent a significant risk of serious injury to young children in the event of a head-on collision. It is therefore essential to refer to the crash tests carried out by ADAC to ensure your child's safety.
Most group 1 2 3 car seats do not have sufficient recline for younger children before the age of 2, which can make the sleeping position uncomfortable and unsafe. Although approved from 9 kg or 76 cm for some models, the minimum settings are often not suitable for smaller children with a harness or shield that is too large or badly positioned.
It's important to try out the car seat before buying to make sure it's really suitable for your child's height and weight. Wherever possible, we recommend that you use a baby cosy or a rear-facing car seat for added safety, as these models offer up to 5 times more protection for your child.

Characteristics when choosing a Group 1/2/3 car seat
Your child's height and weight
Your child's weight and height are the most important factors to take into account when choosing a Group 1 2 3 car seat. It is essential to find a car seat that is suitable for your child's height and weight to ensure his or her safety in the event of an accident.
Safety first and foremost
Safety is the first thing to consider when buying a group 1/2/3 car seat. Check that the seat is ECE R44/04 or R129 (i-Size) approved. Also check that the seat has a five-point restraint system, a height-adjustable headrest, reinforced side protection and an easy-to-use safety belt.
Comfort and convenience
A comfortable car seat is also important for your child, especially if he or she is going to spend long hours sitting in it. Check that the seat has comfortable padding, a height-adjustable headrest, a padded headrest and padded armrests for optimum comfort. Models with removable, machine-washable covers are also practical for busy parents.
Easy to install
Make sure the car seat is easy to install and use. Models with an ISOFIX installation system are easier to install and safer than those that use the vehicle's safety belt. Models with installation indicators are also useful for ensuring that the seat is correctly installed.
