DS-266 is an armchair by Stefan Heiliger for DeSede. The Sedex upholstery and frame are covered with wadding. Seat and back with strap suspension. Steel profile frame and panels. Glides for hard and soft floor coverings.DS-266 is a seat that suddenly transforms into a comfortable recliner. In fact, DS-266 condenses more than 30 years of designer Stefan Heiliger's work into a highly individual sculpture characterized by a passion for geometric shapes and simple ergonomic functions. All it takes is a slight shift of body weight and someone who was just sitting upright can immediately assume a different position. An unusual, masterfully realized look gives this sculptural hybrid a graceful roundness. Manual back adjustment for sitting and lying positions.
