Mifold is designed to work without a latch system. Regular booster seats lift the child to be in the position of an adult, Mifold does the exact opposite. Instead of lifting the child up it actively holds the seatbelt down, positioning it correctly on the hips and on the shoulder of the child. A latch system does not help with this mode of operation. Also, there is no installation required with Mifold, it is designed for 'quick-in-quick-out' usage for every journey in every type of vehicle.
