The person designing a chair is making a decision about another person’s hours.

Design is a decision made in advance about somebody else’s body. A chair is not an object so much as a proposal about how a person will sit for six hours, where their back will ache by four, and whether they can get up easily at the end. The maker will never meet most of the people who live inside that choice, which is precisely why the responsibility is real.

Whatever you make or arrange, picture the tenth hour of using it rather than the first minute. The first minute is easy to design for and is not where people spend their lives.
