Very rare desk chair by Felix Kayser. Model K 49. Old version from the 1930s. The armchair comes from family ownership in 3 generations. In 2017, the chair was completely restored and covered with a matching upholstery fabric. Very good condition. The wooden frame was made of ash. The fabric is undamaged and clean. The armchair is an object and a collector's item. Very stable, comfortable and ready to use. I have official proof of authenticity such as vintage catalogs, designer records, or other literature sources and take full responsibility for any authenticity issues arising from misattribution
