Kasper Salto was trained as a cabinet maker from 1985 to 1988 at the workshop of Jørgen Wolff in Hellerup, Denmark. In 1989 he studied Industrial design at The Danish design school in Copenhagen, and later he spent a semester at Art Center College of Design in Switzerland. After his graduation, he worked as a freelance designer at the studio of Rud Thygesen where he met Peter Stærk, the founder of the well-known Danish Furniture brand Botium. Peter Stærk became the manufacturer of the Runner chair, which not only became well known in Denmark but was also awarded five international design prizes including the Japanese G-prize. The design of the Runner chair started Kasper Salto’s career. At the Danish Cabinetmakers’ Exhibition in 1997, the chair was spotted by Bjørn Stegger, design manager of the Danish furniture company Fritz Hansen, an encounter that led to a long-lasting relationship.

Kasper Salto founded his own studio in 1998, working with Fritz Hansen and developing successful products from 1999, such as the ICE series, LITTLE FRIEND table and the NAP series. The ICE chair series has achieved great sales figures all over the world and also received the French design award, Le Grand Prix du Design. In addition to teaching at The Royal Danish Academy of Fine Arts, Kasper Salto has served on several boards, including the Association of Danish Wood and Furniture Industries and the Danish Crafts Council. His furniture designs have sold to prominent institutions, such as The National Art Center, Tokyo, and the Lousiana Museum of Modern Art in Denmark. In 2004 he co-founded the design company Salto & Sigsgaard with architect Thomas Sigsgaard, working mainly in the fields of product, lighting and interior design.
In 2011, they were invited to take part in the prestigious competition on new furniture for the Trusteeship Council Chamber at the HQ of the United Nations in New York. They won the competition. The Trusteeship Council Chamber was originally designed by Finn Juhl in 1950s, and like the entire UN building of the UN building, it was in need of comprehensive restoration. Today, the room is widely viewed as one out of the three finest examples of Danish architecture outside Denmark.
