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.”
