Since 2003, Kasper Salto, designer, and Thomas Sigsgaard, architect, have been working together on design projects in their studio in Copenhagen. Kasper Salto completed his formal training as a cabinetmaker in 1988 before qualifying as a designer, graduating from the Danish Design School in 1994. Thomas Sigsgaard qualified as an architect in 1995; he has worked for Vilhelm Lauritzen Architects, among other design firms. As a team they worked within lighting design before winning the competition to design new furniture for the UN headquarters in New York. Their prize-winning design comprised new tables and the "Council Chair". In 2014, Salto & Sigsgaard have designed the Guest chair for Montana. Guest is the answer to the question: What to do with the extra chairs in the future, when urban space, both at home and in the work place, is at a premium? Stored away on the shelf on a daily basis, Guest unfolds into a comfortable guest chair in just six seconds.
