The soft sweeping legs and curved crestrail of the klismos chair set it apart from most everything else the Ancient Greeks did. Their stools had harsh angles. Their stone thrones were cold and cumbersome. Their beds (klines) were simple. When it came to furniture, the ancient Greeks were about function and practicality.
The Greek house was unassuming, humble with limited decoration. The only place to sit was mainly on backless stools -- three and four legged stools, box stools, rectangular stools and folding stools.
But the Greeks, with their zeal for the human body, designed a particular chair that married beauty and comfort. Perfected by the fifth century BC and popular throughout the fourth, it echoed the rhythm and precision, clarity and proportion, and even order of their architecture. It was the most important creation in the history of the chair.
The klismos chair had grace, symmetry and perfect proportions.
No original klismos chairs reached modern times. It was made from wood which didn't survive through the times. But the Greeks left a rich history of bas reliefs and vase paintings of the chair.
