What are the age and weight requirements for Mifold?

Mifold is designed for children aged 4+ years. However, car seat regulations can be quite confusing and are different in each country; they can be based upon age, weight, height or a combination of all three. In the US and Canada, Mifold is designed for children weighing from 40 Ibs to 100 lbs (18-45kg) and between 40-57 inches (100-145cm) tall. In the EU the weight range is from 15kg up and until a height of 150 cm.
