Seam is characterized by a unifying line which goes all over and draws the sofa’s shape. The visible seams, analogous to leaf veins define its organic structure. The straight outside outlines come in contradiction with the softness of the padded seat, armrests and backrest. The thin feet, made of square section bended bar follow on from the seams, and bring lightness. Seam is a unique system of sofa regarding its inclined cut on sides. It makes it more welcoming just like its shape.

Winner of the Interior Innovation Award 2015, iF design award 2015 and Golden Key Award 2016.

Design means everyday culture. It helps us to enjoy and simplify life. We are fascinated by the process that starts with an idea, becomes substance and hopefully results in a long and pleasurable use for its qualities. That’s how we understand reasonability and sustainability.

Moritz Böttcher and Sören Henssler founded their Berlin based design studio in 2007. In 2013 the designer Nikolaus Kayser joined the team. Since 2014 the trio is working under the studio name Böttcher Henssler Kayser in the fields of consumer product, furniture and lighting design with companies such as ANTA, Böwer, Johanson, Mater, Normann Copenhagen, Prostoria, RIG-TIG, Schönbuch, Vertigo Bird, WON and Zero. 

While still in their studies they received the iF product design award 2005, the red dot design award 2005 and 2007. Honours continued in 2010 with the Europe 40 Under 40 by The European Centre for Architecture Art Design and Urban Studies. In 2011 and 2012 they won again the red dot design award. 2013 they were rewarded with the prestigious red dot „best of the best“. The German Design Council nominated the studio in 2014 and 2015 for the German Design Award. In 2015 they were honored with both, the Interior Innovation Award and iF design award. Their projects have been published internationally in books and magazines.

Since the completion of his degree in 2005, Sören Henssler works independently from Berlin.
