The key components of a traditional klismos chair are: saber back and front legs; wide, curved tablet back rests; and curved stiles (the posts leading from the back legs to the back rest). In ancient depictions, the stiles are typically a continuation of the back legs, forming a gentle S-curve. In antiquity, klismos chairs were lightweight wooden chairs that could easily be moved around a room. Apparently, they are mostly associated with important female users, since most people sat on three-legged stools, but there is ample visual evidence of men sitting in klismos chairs, as well (eg. image 4). Evidence of klismos chairs essentially disappears by the middle of the 4th century BC, when they must have fallen out of fashion.
In the late 18th century, archaeological excavations of ancient sites led to an intense interest in historically-accurate Neoclassicism, and images of any discoveries were widely disseminated. Furniture makers were immediately inspired by the klismos chair, including Georges Jacob, Thomas Hope (image 5) and Benjamin Latrobe (image 6). These designers did not always take the form literally, but used it as inspiration. Designers in the early 19th century often left the front legs straight, so there was more in common with the more Roman Neoclassicism of the generation before. Many designers embellished the simple klismos form with back splats, finials or stretchers, while others painted Neoclassical motifs in a Pompeiian palette onto the wood (images 5 & 6).
In the 20th century, the designer T. H. Robsjohn-Gibbings produced many literal translations of the Attic images (image 7), the stark, fine lines of the chair revealing a startling modernness. Subsequently, contemporary designers have used the familiar klismos form as a point of departure again and again.
Why is the klismos chair such an enduring form? Perhaps because the graceful sweep of the curves balances its classical sobriety. Or, on a practical level, because the curved back rest is comfortable and the curved legs offer extra support. Or because, like any true classic, it can be adapted a million ways while still maintaining a sense of tradition.
Whatever the reason, it is literally the only ancient furniture form that, in its most faithful reproduction, can still fulfill today's practical and stylistic requirements.

Sources: The Donghia Anziano shown in image 11 retails for about $1800. Ethan Allen makes a Hollywood Regency-style variation on the klismos that retails for $349. And Restoration Hardware has a gorgeous outdoor cast aluminum klismos chair on sale for $299. If money is no object, there are always lots of good options on 1st dibs. I like this pair of Indian inlaid klismos chairs from William Laman for $1650, and of course you could go for it and buy a Robsjohn-Gibbings original from J.F. Chen. But my favorite is this sexy brass and patent leather version ($4800) at Dual that shows how versatile the form really is.
