I appreciate a slight yield, lightness of weight, some motion if possible, because in moving about, the human body determines... the comfort and the measurements of its environment... the human measure is still the strongest factor. But coming back to the chair, there are certain motions we go through - we like to lean back, like to toss things - and if the chair's adaptable it responds and it's almost like wearing a comfortable coat; you really don't know you have it on.
