3. 5 critical mistakes when choosing a car seat Rant 9–36 kg

Even experienced parents often fall for the tricks of marketers or simply do not take into account key nuances. Here top 5 mistakesthat may cost the safety of your child:

Mistake 1. Buying for growth

Many people take a chair 9–36 kg for a one-year-old baby weighing 10 kg, hoping that it will last until school. But in reality:

• 🛑 Child under 4 years old necessary five-point harness system (as in group 1). In universal chairs, it often weakly fixes the shoulders.
• 📉 Models without headrest width adjustment (for example, Rant City) do not provide sufficient side protection for babies.

Solution: If your budget is limited, choose chairs with removable inserts for group 1 (for example, Rant Sport 9-36).

Mistake 2. Ignoring the weight of the chair

Rant Grand weighs 9.5 kg - it is inconvenient to carry it from car to car. If you frequently transfer (for example, between two cars), pay attention to Rant Travel (weight 6.8 kg) or Sport 9-36 (5.2 kg).

How to check the weight of a chair before purchasing?

The characteristics on the website often indicate “gross weight” (with packaging). To find out the real weight, look for reviews with photos of scales or ask the seller: “How much does the chair weigh without a box?” For example, Rant Comfort Fix the package weighs 11 kg, and the chair itself weighs 7.3 kg.

Error 3. Incompatibility with the car

Not all chairs Rant suitable for small cars (eg Daewoo Matiz or Oka). Problems arise with:

• 🚗 Narrow rear seats: armchair Rant Grand 48 cm wide may not fit next to the booster.

Solution: Before purchasing measure:

• 📏 Rear seat width (minimum 50 cm for group seats 2/3).
• 📐 Distance from the seat back to the ceiling (for high chairs like Comfort Fix you need at least 60 cm).

Mistake 4. Covers that cannot be washed

• 🦠 Development of bacteria and fungus (especially if the child often drinks in the car).
• 💸 Additional expenses for dry cleaning (from 1,500 ₽ per procedure).

Solution: Choose models with removable covers (for example, Comfort Fix or Grand), which can be machine washed at 30°C.

Mistake 5. Neglecting lateral protection

According to IIHS, 40% of child injuries in road accidents occur during side impacts. In the armchairs Rant The level of protection varies:

• 🛡️ Grand and Comfort Fix: reinforced polystyrene foam inserts, ADAC rating "excellent".
• ❌ City and Travel: minimal protection, "satisfactory" rating.
