The sofa's upholstered section is loosely placed on a visible,
solid wood frame whose top row holds the seat securely in
place.
Koch believed in honest design and was opposed to legs that
appeared seemingly out of nowhere, seeing this as cheating. He
similarly disapproved of using upholstery to hide cheap wood and
felt that every design's construction should be of high quality
throughout.
The Model 52 Sofa's visible frame structure exemplifies the
Danish functionalists' idiom of separating the bearing part from
the borne part - or the frame from the seat - to fully show the
furniture's construction and highlight the high-quality, natural
materials, thus making the construction a design feature in and of
itself.
The frame is crafted from solid wood and the seat/back is
upholstered with leather.
