Designing a good chair is a much more challenging task than we might think. To begin with, several factors must be addressed, such as ergonomics, aesthetics, materials, functionality and durability. In addition, it is essential to define the purpose for which it will be used: an office chair has different requirements than a reading armchair or a dining chair, for example. Only when all these elements are carefully balanced and thought-out can you achieve a truly excellent chair. And often, a good design can end up triggering many other variations throughout the years.
