Good Design is like anything else 'good': it seems easy and seamless and nobody sees the 'sweat behind the smiles'. When one sees truly good Design one can be sure that the Designer is not only very talented but that they also have a great eye for detail and are obsessive with regard to accuracy.
Take this chair, for example. 9/10 times this chair will be facing outwards and the back of it will only be viewed very occasionally: the Designer in question, however, was concerned with the 1/10 times that the chair might have been viewed from the rear and Designed the back in an angular, striking manner. Notice the colour of the wood: it is just the right tone and exudes a confident style that makes this chair a winner from every angle!
