A bit of a meta-quote:

But in choosing a chair we follow the dictates of our eyes, for better or for worse, more often than those of our "ischial tuberosities," and the hammocklike Hardoy looks comfortable. [Joseph] Rykwert correctly assumes that "the buyers of Hardoy chairs, like many other customers for design goods, are guided in their choice by promptings quite different from the dictates of reason." And he adds a conclusion worth remembering: "The very fact that they do so should be a matter of interest to the designer: nothing human should be alien to him."
