Design Constraint

Partner Needs

Because my project partner has scoliosis, she wanted a chair that would remain comfortable while she worked.

  • Partner-specific design
  • Scoliosis
  • Working posture

Measured Model

I built a 1/6-scale mannequin from her measurements, including tolerances for comfort and loose clothing.

Form Testing

I developed three chair forms around a 135-degree seating angle, then used a full-size model to check proportions, posture, and areas needing reinforcement.

  • Three form concepts
  • 135-degree angle
  • Full-size stress test

Final Model

The final pieces were laser-cut and assembled by hand. My project partner could sit comfortably, use a laptop, and spread her arms.
