SLL18 is a re-edition of a chair created in 1958 by Belgian modernist architect, Léon Stynen. To celebrate the 60th anniversary of this design, a polypropylene version was added to the SL58 collection. During the development of the SLL18, the original design was respected, with a few minor adjustments. This makes the SLL18 the perfect ’21st century version’ of the beautiful classic. Same design, stackability and comfort in a new polypropylene jacket.
