This rare lounge chair was designed by Eric Bertil Karlén and produced by his company Firma Rumsinteriör in Sweden in the 1940s. The elegant shape of the design is emphasized by the buttoned wing shaped back and seat. The elm wood frame consists of single side slats and tapered legs. The chair has been newly upholstered in an ember colored de Le Cuona fabric, a textured linen and wool with three twisted yarns for subtle variation in tone and texture. The elm wood frame with a natural patina. The natural, beautifully textured fabric, elegant silhouette, and buttoned back and seat details give the chair a refined and timeless appearance.
