i-Size

The car seat meets the requirements of the European safety standard i-Size (ECE R129). Within the framework of this standard, it is assumed that child car seats are classified according to the height and age of the child, and not by weight (as was previously the case). It is also mandatory to fasten the retaining device using the Isofix system (see “Isofix fastening”). In accordance with i-Size requirements, car seats must be installed rear-facing until the child is 15 months old or reaches a height of 105 cm. All i-Size certified car seats must pass a side impact test. Chairs and cars that meet the requirements of the standard are marked i-Size, which confirms their full compatibility.

Recommended height

Recommended values of the minimum and maximum height of the child (in centimeters), at which the car seat provides optimal safety and comfort. The parameter must be taken into account when choosing a child car seat along with the age and weight groups, because children of the same age can have different heights and weights.

Adjustments

Backrest tilt adjustment. The backrest tilt can be adjusted. This point is different for various weight groups. In groups 0+ and 1 not the backrest, but the whole seat tilts against the fixed base, and in groups 2 and 2/3 only the backrest tilts. The possibility of adjusting the backrest tilt is important if the child is in the car for a long time – by tilting the backrest you can let the child sleep or rest.

Headrest height adjustment. According to safety requirements, the child's head should not be more than one third above the headrest, so it is necessary to adjust the headrest as the child grows.

Harness height adjustment. The ability to adjust the height of car seat harnesses — such a need arises as the child grows.

Backrest width adjustment. The ability to adjust the width of the backrest allows you to optimally adjust the car seat not only for constantly changing height, but also for the child's complexion.

Horizontal position of a backrest. The backrest of the car seat is horizontal. The horizontal position is optimal for babies under the age of six months, since it avoids unnecessary stress on the spine, therefore group 0 car seats usually have this function.

Removable backrest. It is possible to comp...letely remove the backrest of the car seat. This function expands the possibilities of the seat: it can be used both for its intended purpose, with a backrest, and as a booster (for more information on boosters, refer to "Weight group 3").

Swivel system. The seat swivels relative to a fixed base. This makes it easier to drop off and pick up the child: during these operations, the seat can be turned to face the car door, and when driving, it can be positioned in or against the direction of travel.
