The Kassl X Pillow Central Seater from BD Barcelona Design is an armless seating unit whose form is defined entirely by three stacked, independently cushioned volumes. Designed by Muller Van Severen, each cushion is upholstered in lacquered cotton developed by KASSL Editions, a fashion brand whose signature technical fabrics originated from production offcuts, giving the piece a distinctive tactile surface. A powder-coated tubular steel structure sits beneath, with soft or hard flooring glides included.
