This is a simple three-leg African stool.

The approximate height is: 10 1/2"

The approximate diameter of the circular top is: 11"

I found this in about 1987 in a Milwaukee shop specializing in international antiques and indigenous crafts.  It has served me well through family moves to Chicago, New York, and Seattle as a sculptural display object, but I have to confess it has often been used as a regular stool!  

I don't know the historical provenance of this item, so sorry, but I have seen examples online from Kenya (Kamba? Akamba? Turkana?) that look very similar. This stool form is identified by a simple unadorned carving from a single piece of wood, with a rounded and worn-polished seat, with three flattened legs splayed outward toward the ground. Please check out some of the stools in the Lynn and Michael Noel Collection housed at the Spurlock Museum University of Illinois, to see some examples of similar Kenyan stools (e.g., catalog 2012.03.2623). 

On the other hand, some famous tripod style stools from the neighboring country of Ethiopia (Oromo ? Galla ?) also bear resemblance.  Austrian architect Adolf Loos designed his famous "Theban stool" in about 1903, which many believe was based on an Ethiopian Oromo stool design. 

The wood is solid and firm throughout, but there is a very old crack in the seat as a result of the aging and drying process (see at least one example of a vintage repair of a similar crack in the Spurlock Museum collection: catalog 2012.03.2623). This does not affect the stability or balance at all. Nothing moves in this stool. The top surface is well polished and patinated from many decades of use. There are other dings associated with the age and use of this object, as shown in the photos. 

Completely non-smoking, no pet household, so there are no issues in that department. 

Local pickup in metro NYC area is best, but secure double boxed shipping is possible at cost.

Thanks for looking! This is a very cool stool. My kids loved it growing up.
