This is a beautiful, adjustable working chair by iconic Dutch designer Friso Kramer. The frame is made of high quality grey metal and it has a plywood seat and back. This gives the piece a modern, industrial style. The seat and back are both adjustable in height seperately, making it comfortable for many different users and situations. It would be a practical solution for any working space, or a unique addition to an interior looking for a touch of industrialism! It remains in very good, vintage condition with minor wear consistent with age and use, preserving a beautiful patina.
