Cardboard Chair Challenge
Design a chair constructed of corrugated cardboard that can support a 200-lb person. may not use glue or tape to fasten any component of your chair together. May use tape as a temporary support, but all of this material must be removed when the final evaluation begins. May use other materials as fasteners (i.e. hardware) but they must be approved by the instructor.

Reasons why you chose your design
Life Vest Challenge Presentations Slide 3 should include: Pictures of 3 sketches Reasons why you chose your design
13
Cardboard Chair Challenge
We chose this design because we thought the triangular base would support the 200 pound weight. We chose this design because we thought the lounging design would provide more comfort.
14
Life Vest Challenge Presentations Slide 4 should include:
Sketch of the design you test List of modifications you made during trials

Cardboard Chair Challenge
Our chair easily held the weight of the instructor, The back piece did bend, still provided some support.
18
Life Vest Challenge Presentations Slide 6 should include:
Thoughts from your team reflections What things went well during challenge Struggles and how your faced them Changes you would make next time
19
Cardboard Chair Challenge
Our team really struggles during the design phase. We had a hard time converting our measurements to 1/10th scale. WE also struggled to build our scale model. Upon reflection, we found that these struggles made our construction phase go much smoother. We had worked out many problems we would have faced during the design phase. After reflecting, our team would make the following changes to our design: Make base 1.5 feet tall instead of 2 feet tall. Provide more support in the back piece.
