Description

William Armbruster's donut stool for Edgewood Furniture Co.
The stool was featured in the Museum of Modern Art's "Good Design" Exhibition in 1950. Excellent example of early American modernist design.
In very good un-restored condition.  These are very rare to find. And even more rare to find un-restored.
It has a tag that includes a 1940s-50s era New York paper inspection stamp. New York was the location of Edgewood Furniture.
It has some wear spots in the fabric and paint chipping on the legs.
