Arnhem Sofa Modular Couch Designed by Sebastian Herkner


A truly iconic item from our collection and named after the city where De Vorm was born. Arnhem Sofa was designed with functionality in mind. It comes with no restrictions in its shape and look, allowing designers the freedom to adapt the form for themselves.


Designed by Sebastian Herkner 

For Sebastian Herkner, form always follows function. His designs are recognised by simple techniques and traditional materials leading to a product that needs no explanation. Herkner is not concerned about current trends or consumer criteria - he strives to add value to the users by making his creations functional, sustainable and intuitive. 

“There is a sensitivity and identity to my work that emphasizes the function, the material and the detail. I transport and interpret characteristics from various contexts of society and culture and implement them in new artefacts. This character infuses the most everyday objects with respect and personality. In this manner, seemingly contrary things can experience esteem.” 

Upholstery by Kvadrat 

We don’t settle for less when it comes to choosing materials for our products. That’s why the upholstery of Arnhem modular sofa is made from contemporary high-quality fabrics by Kvadrat. Since 1968, Kvadrat has been leading the field in textile design and innovation.
