How do I choose the correct size for the Fosta children's posture corrector 652b-3?

Use the height and chest measurement guide printed on the packaging of this model. In this model, size 3 is the larger option, so it is intended for a child who is closer to the upper end of the height and chest ranges shown on the package.

To get a reliable measurement, have the child stand straight and measure around the chest at its widest point, then record height. Compare both numbers with the size table on the package, not with the child's usual clothing size, because posture corrector sizing can differ between manufacturers.

If the product is too small, the lumbar belt may ride up and the shoulder straps may feel restricting. If it is too large, the belt will not stay anchored around the lower torso and the figure-of-8 straps will not guide the shoulders effectively. If the child is between sizes, or you are not sure which range applies, check the fit with the corrector on before regular use, and ask a paediatrician, orthopaedist or physiotherapist for guidance.
