• The short and somewhat glib headline answer is that it is an incredibly comfortable design of back rest, which it is.  However, allow us to explain it’s origin…

  It is not a ‘chair’ as some think of it, it is a back rest design for an office chair.  It was designed by a German professor who no matter how hard he tried, could not find a comfortable chair.  He solved this himself by fashioning and playing with off cuts of foam which he stuck on his office chair.  Eureka, he found just the right level of support and comfort he was missing all along.

  Being of an entrepreneurial  mind, the professor took his idea for his newly formed back rest to many seating manufacturers with a view to producing it en-mass. No company took interest until he spoke with Grahl Gmbh, latterly Rohde & Grahl.

  Grahl are an office seating and furniture manufacturer in northern Germany who have always had workplace ergonomics as a top priority in their thinking and design processes.  They saw the potential in the design and took the Professor’s initial concept and worked together with him to create the now world famous, DuoBack backrest.

  It has continually evolved and improved through much investment in to a back rest that is highly regarded today.  Medical professionals, physiotherapists and insurance companies recommend DuoBack for its dynamic support and postural benefits.
