I am almost through a book called Rethinking Sitting, which discusses different ergonomic design styles of chairs. The author, a commercial designer of chairs, has developed many different models which are quite distinct from the typical form that you or I would recognize as a chair. Of course, he feels that his chairs have distinct ergonomic advantages over typical chairs.
This quote is from the book, and I think that it applies to designers of all fields.
“One of the most common limitations in product development is conventional wisdom.
– Peter Opsvik, from his book, Rethinking Sitting
