Mårten Cyrén studied at the wood crafts department of Nyckelviksskolan in Stockholm in 1980-81 and at the Haystack Mountains School of Crafts in 1981. From 1981-85 he studied interior architecture and furniture design at Konstfack University of Arts, Crafts and Design in Stockholm.
In 1984 Cyrén founded his own design studio and from 1985 he has worked as a consultant for IKEA, Made Architects (1986-89), Inredningsgruppen (1989) and Bergström architecture (1990-91). During 2000-2001 Cyrén was a lecturer in furniture design at the Konstfack University of Arts, Crafts and Design and at the University of Gävle. From 2003 to 2008 he was a member of the board for foundation of Nyckelviksskolan and from 2008 he was once again a consultant for IKEA.
Cyrén has worked as an interior architect for among others the Swedish Art Council and Pharmacia Upjohn. He has designed light fittings for Fagerhult and Zero as well as glassware for the glasswork Pukeberg.
In 1990 Cyrén designed the Klyka chair for Miljöexpo together with Jonas Osslund. Klyka was given the Excellent Swedish Design Award, which Cyrén has received no less than seven times since then. Klyka is a part of the permanent collection at the Swedish National Museum and at the Museum of Furniture Studies.
Since 2017 Cyrén has been a co-owner of the design studio and manufacturer Storängen, which he founded together with Torbjörn Källberg. In 2020 Cyrén’s son Carl, also an interior architect and designer, replaced Källberg as CEO and co-owner. Storängen is best known for the chair Storängen, an offspring to the classic Windsor chair but with a tall back.
