Cardboard chairs

  1. 1. Carter, Eric, Kevin and Olivia
  2. 2.  We decided that we did not think that it was possible to make a strong, economical chair out of cardboard that had legs. We knew that triangular prisms hold up well in construction, so we used that. We based the height of our chair on the height of a desk chair. This information was attained by conducting a survey of the class.
  3. 3.  Our chair was made almost entirely out of cardboard. Other than that, we just used some glue for the joints.
  4. 4.  We used 16.2 square feet of cardboard. It cost $2 per square foot, so our chair cost $32.40.
  5. 5.  The base is a triangular prism that had sides that were 15” each. It also had another triangular prism inside of it that had sides of 7.5” each. The whole base was 17” tall.
  6. 6.  Our seat was made out of two pieces of 13”x15” cardboard. It was rounded at the front for aesthetic purposes and also to provide room for your legs. There were also some supports under the seat to make the seat on a 10⁰ incline.
  7. 7.  The back of our chair was one piece of 19”x15” cardboard. It was shaped purely for aesthetics. Two sets of four long, skinny pieces connect the back to the base of chair and provide all of the support. The extra room between the chair back and the supports allow for variable reclination.
  8. 8.  Something that we could have avoided was the supports underneath the seat. By initially angling our base to fit the requirements, we could have possibly made a stronger seat and a better looking chair.
