Set of Four Vintage Rush and Iron Swiveling Bar Stools by Arthur Umanoff

Set of four Arthur Umanoff for Shaver Howard bar stools composed of wrought iron frames with birch-slatted seats (ca. 1950s, USA).
Modernist, rectangular rush back adds a striking contrast to an otherwise modest form.
Swivel seat allows for full 360 degree mobility.
The seat height is 28.75″, so these can be used as bar or counter stools, depending on the surface height.
Wrought iron frames are in original condition; light marks present. Birch seats have been conservatively refinished; minimal wear remains. The rush is in excellent, original condition with only minor wear.
Listing is for the set of four.
