How is it that the product description says: "15 - 36 kg, 100 - 150 cm" and according to legal regulations, such a seat without a backrest may only be used if the child is 125 cm tall and weighs 22 kg. In other words, 25 cm and 7kg more as stated in the product description. This means that families will certainly buy this seat even though their child is still too small.
