Project developed while studying at the University Rafael Landivar in Guatemala City. The main goal of the project consisted of making a seat from recycled cardboard,

 

The project had a limited budget of $150 to spend on research and prototype. Inspired by the shape of pyramids, I learned that this figure with three faces could absorb enough force. By inverting two pyramids I got better results for stronger resistance. I made a durable and resistant stool using packing tape, which held the entire structure, and varnishing with several layers of wood glue 

 

The project exceeded the goals. The prototype and research cost $50, a stool which resists up to 250 pounds (standing or sitting) , 100% recycled cardboard, and after five years the prototype still works.
