Set of two innovative split seat stacking chairs designed by Richard Schultz for Knoll Associates circa early 1960's. One chair has the 320 Park Avenue Knoll Associates label attached to one of the chairs dating these prior to 1969 when Knoll moved to Madison Avenue. These could be used as dining, side, or accent chairs. The chrome propeller bases do not swivel. These have been restored with new foam and vintage woven Knoll style fabric.
