A furniture manufacturer is considering a line of seating products to be fabricated by cutting and bending a recycled plastic material available in large sheets. Create a prototype of at least

one possible chair design by cutting and bending a sheet of paper or cardboard. (You may wish to design the chair with a sketch first, or just start working with the sheet directly.) What can you learn about the chair design from your prototype? What can't you learn about the chair design from such a prototype?
