This portfolio shows prototyping of better solutions for inner city material handling. There are aluminum and steel versions of the grocery cart. The first products on the market will be the steel version. It is designed to carry a full load of groceries, plus your dry cleaning or anything else you need to get home. It is also a great item to move laundry. If you need to negotiate curbs, cobblestones or steps to get home, the tilt-back is your solution.
