It is a suitcase with an integrated seat that folds away when not needed. A parent or caregiver must keep the case under continuous control while one child aged 2+ sits on the seat on a flat, level surface. It remains luggage first—not a stroller, toy, vehicle restraint or substitute for adult supervision.
