Best Infant Car Seats, Depending on the Weight of the Baby
Best infant car seats are one of the most important purchases you will make as a new parent. In our testing, we consider Ease of Use, Baby Weight and Height Ranges, Safety and Car Size Types.
|Group||WEIGHT||APPROXIMATE AGE (should not be used to choose the type of seat)|
|0||Up to 10 kg||up to approximately 9 months|
|0+||Up to 10 kg||best Infant car seats: up to approximately 15 months|
|I||From 9 to 18 kg||from about 8 months to 3 or 4 years|
|II||From 15 to 25 kg||Best Infant car seats: Approximately, from 3 to 7 years old|
|III||From 22 to 36 kg||Car seats: from 6 to 12 years old|
Height is another determining factor, being even more important than weight. All child restraint systems approved under the ‘i-Size’ standard are based on height.
The weight is, in any case, more important than the age. Since it is the weight that determines the resistance. That the best infant car seat must offer (that is, if the child weight a lot, in case of an accident the structure of the chair could not endure the effort and break).
Currently, we find small chairs for children: from 40 to 85 cm and from 45 to 105 cm.
In the coming years and as the following phases come into force. The number of seats that will be governed solely by height will increase.
Below is a more detailed description of each type of seat:
GROUP 0 or 0+ / From 40 to 85 cm and from 45 to 105 cm (i-Size)
For babies of 0 to 10 kilos of weight (normally up to nine or twelve months of age, although age is a guiding criterion and the important thing is the aforementioned weight), in the case of group O.
And for babies up to 13 kg (usually up to twelve or fifteen months of age, although, we insist, age is a guiding criterion and the important thing is the aforementioned weight), in the case of group O+.
If we take into account the approval ‘i-Size, we find seats from 40 to 85 cm (up to 1 year approximately) and from 45 to 105 cm (from 6 months to 4 years approximately)
The seats of this group, in turn, can be of two types: baskets or cuckoos, first, and baby seats, in second. Carriers, also known as “baby carriers”, are less common. But some are also approved for use in the car(it is very important to check in their instruction manual that they are actually approved for such use).
The baby travels lying down, in a very natural position. But in some chairs of this type is only subject with a belt located on his belly. So that, in the event of a side impact, the baby is less subject.
(although in the market there are and models of baskets with harnesses or belts in the shape of “Y” that significantly improve the protection in case of lateral impact)
Baby chairs are the most common type. Often they are popularly known as the trade name of “Amazon” (actually, the name of a manufacturer of seats and children’s products). Best Infant Car Seats should always be installed facing backward.
• IMPORTANT: the rear-facing baby seat.
• NEVER: must be installed in a seat with a front airbag, unless the airbag has been previously deactivated.
GRUPO I for best infant car seats
For children from 9 to 18 kilos
(normally between one and three years of age, although age is an indicative criterion and what is important is the aforementioned weight)
They consist of seats that are fastened to the vehicle with the safety belt. Or with the new ISOFIX system and where the child normally travels attached to the seat with a safety harness. And looking either forward (which is the most usual) or backward (as is common in the Nordic countries).
• IMPORTANT NOTE:
In a young child, the relative weight of the head with respect to the body is greater than in an adult. In addition, the neck is not fully developed. For all these reasons, it is advisable to use as much time as possible a system oriented backward.
Group II for best infant car seats
From 15 to 25 kilos (normally between three and seven years, although age is a guideline and what is important is the aforementioned weight).
They consist of a cushion and a backrest that is normally placed on the seat of the vehicle. The child sits on the child seat and fastens the seat belt of the vehicle. This type of child seats “elevates” its occupant so that the seat belt of the vehicle fits correctly. Passing through the most resistant areas of the child’s anatomy (hips, sternum, and clavicle).
Group III for best infant car seats
From 22 to 36 kilos (between six and 12 years of age, although age is an indicative criterion)
They consist of a cushion, in some cases, with backrest, which is normally placed on the seat of the vehicle. As in the previous group, the child is placed on the child seat. And the seat belt of the vehicle is fastened. This type of child seats “elevates” its occupant so that the seat belt of the vehicle fits correctly to the body of the user. Passing through the most resistant areas of the child’s anatomy (hips, sternum, and clavicle).
The next regulatory changes advocate the use of the lift on all lifts (only approval of these CRS)
It is worth remembering that some seat models serve several weight groups. Thus, it is common to find seats of groups 0 / I (which can be used from birth until the child reaches 18 kilos). And seats of groups II / III (from 15 to 36 kilos). As a seat covers more weight groups. It is increasingly difficult to guarantee the same level of safety for all of them.
For this reason, it is common for many of the safest seats to be those that serve only a single weight group. Parents should, therefore, decide whether to acquire a seat for each stage or one that serves several.
