Quarto was designed by Torsten Thorup and Claus Bonderup back in the 80'es, but is still going strong due to its classic circular shape. However, the Quarto from Focus Lighting differs from the many similar products because it ends up in a cylindrical shape. This completes and adds harmony to the shape. Throughout the years Quarto has proven its ability to both adding quality to and adjusting to its environment.
