child will be more comfortable at a shorter table in
relation to his or her seat height.
This graph and chart are based on average recommendations from several sources, and should only be used as a guide. By measuring the child as directed above, you will ensure the best t possible. If
measuring the child is not practical, use this chart as a starting point. Consider whether the child’s build is bigger or smaller than other children of the same age. If you are still unsure of what size chair
to order, go the next size up to give your child room to grow!
