Designed for multi-function travel, the MiaMily x WonderFold Carry On Luggage bag universally configures into a ride on suitcase for children or a portable seat for adults, allowing your child to quickly and conveniently travel with you atop the travel suitcase or providing a resting place for adults when standing for long periods of time. When traveling without a child, the seat on this spinner suitcase can be used to safely store a diaper bag, travel bag or a briefcase.
