From what age and with which signs of slouching should one start using the corrector? — Kids Posture Corrector 652B-1

The card gives no age recommendations or signs for which one should start using the corset. All that is known is that it is a children's corset for supporting correct posture, size «S» (waist circumference 50–60 cm, insert length in the corset 20 cm); according to the manufacturer's description it helps keep the back straight, reduces slouching of the shoulders and supports the healthy development of the child's back in everyday life. It is suitable for everyday use.

General recommendation (not a manufacturer's instruction): the corset is an auxiliary device and does not replace physical activity, regular breaks and a properly organised workplace. If the child's shoulders look asymmetrical, there is marked discomfort in the back or you have doubts about the causes of the slouching, consult a paediatrician or orthopaedist before use. For external use only; in case of allergic reactions, stop using it and see a doctor.
