How do I choose the right size and what happens if the corset is too small or too big? — Group corset for children 652b-2

According to the English description, the size of this corrector is 2, and the chart matching height and chest circumference is on the packaging; follow it rather than only the child's age. The straps should hold but not restrict normal breathing or circulation; the corrector must not be overtightened. If the child experiences discomfort, the corrector must be removed immediately and a doctor consulted.

General information (not a manufacturer's instruction): a size that is too small can press and chafe and restrict breathing; one that is too big will not hold the needed position; children grow fast, so it is worth checking the size again after a few months. The product is used on the recommendation of a paediatrician, orthopaedist or physiotherapist.
