This pair of Mid-Century Modern armchairs are by the maker M. Singer & Sons circa late 1950s. They are attributed to American designer Bertha Schaefer and Italian designer Carlo di Carli as these chairs have the noteable earmarks of Schaefer's designs and de Carli's model 162 dining chair. The chairs may be a collaboration of the two designers who worked together on the "Modern by Singer" line, an Italian design inspired collection for M. Singer & Sons. The armchairs have organic sculptural walnut frames with legs connecting in a wishbone form and horizontal armrests. They are newly finished and upholstered in an ecru tweed.

In the 1950s, New York-based M. Singer & Sons collaborated with prominent Italian designers to produce high-end, modern furniture, effectively bringing Italian modernist style to the American market. Key Italian designers included Gio Ponti, Carlo Mollino, Ico Parisi, and Carlo de Carli. These designers worked in conjunction with American designer Bertha Schaefer to create the "Modern by Singer" line. 

New upholstered and refinished.
