The Office ChairRedesign presentation
Bryon Sutherland
Design Principles: Good
Function• 80/20 Rule• Accessibility• Affordance• Flexibility-Usability
Tradeoff• Constraint• Normal Distribution• Convergence
Aesthetics• Aesthetic-Usability Effect• Color• Performance versus
Preference
Design Principles: BadFunction• Affordance• Mapping• Modularity• Segmentation: difficult to
assemble• Weight: chairs are heavy• Surplus: most functions
rarely used• Feedback: no feedback for
bad posture
Aesthetics• Color in the real world• Contour bias• Design by committee• Stickiness• MAYA• von Restorff Effect• Curvature• Dynamics
Iteration 1, the Exclamation PointEye catchingUnstable seatSeems to defy physicsSelf-orienting (sort of)
Iteration 1, problems
• Lead ball is – Heavy (40 lbs)– Expensive– Poisonous– Likely to damage floors
• Chair needs a constraint– Falling backwards very easy
• Welded a flange on rear• No height adjustment
Design alternatives
Final design, Iconoclast
• Removes lead ball issues• Provides backwards constraint• Falls to rest position• No need to self-orient• Keeps freedom in 300°• Adjustable• Modular

Hierarchy of Needs
Office chairs• There are many different
office chairs with varying qualities.
• The best chairs allow the user to ignore the chair and get work done.
• The worst chairs need constant adjustment and draw the user’s attention away from work.
Iconoclast chair• Not a functional chair for
many in population.• Targeted users can
express themselves in new ways with colors and materials.
