At the end of the 1990s, Arper launched an industrial project that took the company into the design field and led to the use of new materials and technologies and a marked change in scale. The encounter with the Lievore Altherr Molina design firm was another important milestone for Arper resulting in a fruitful collaboration leading to a series of new products that would turn out to be classics. They include the family of Catifa chairs which are available in 5 different versions and have sold over a million units since 2001.
Arper has called upon other leading international designers to create its chairs, tables, sofas, stools and small armchairs. Rodolfo Dordoni, Jean-Marie Massaud, Simon Pengelly, and Ichiro Iwasaki have all brought their different cultural backgrounds, thoughts and languages into the company while interpreting the distinctive Arper style: a sleek, sophisticated, contemporary style assuming timeless universal forms capable of fitting perfectly into all settings.
