With its signature flexibility, this adaptation of Carl Hansen & Søns' FK63 system features a stacked bookcase with a total of 14 sliding storage trays. Designed by Preben Fabricius and Jørgen Kastholm in 1963, the enduring minimalist approach focuses on proportion, natural materials and handcrafted details. Fashioned in solid FSC-certified sustainable oak with a veneer back and ashwood trays, the unit can be wall-mounted or be freestanding on the collection's optional slender metal base.
