RideBy is a child seat that is designed to attach to a standard shopping cart, making grocery shopping easier for both, parents and children. It provides a designated place for children, allowing them to move freely while staying secure. Made from metal with plastic components, just like the shopping cart, RideBy attaches with a single screw. To save space, RideBy features a flexible joint that allows the seat to fold when the carts are nested together. The fixed footrest prevents scratches on the cart, and the handle alongside the cart's basket, additionaly protects the child from bumping their head. Thanks to RideBy, shopping becomes a participative and dynamic experience, engaging both the child and the parents.
