Among its many brilliantly conceived variations, Carl Hansen & Søns' deploys its FK63 system in a deep bookcase with a horizontal double-shelf configuration. Preben Fabricius and Jørgen Kastholm's timeless 1963 design features pleasing proportions, an emphasis on natural materials and finely rendered detailing. Crafted in solid FSC-certified oak with a veneer back, the bookcase can be wall-mounted or serve as a standalone on the collection's optional slender metal base.
