For the FKY shelf, four layers of horizontal bars and three layers of slightly inclined vertical bars are alternately interconnected into a three-dimensional structure. Numerous junctures of overlapping sticks provide sufficient surface connection for the stability of the shelf. Deviation from orthogonality enhances the statics of the shelf, but also results in appearance of a structure achieved by random stacking of similar sticks made of various materials. The shelf / room divider is made of combination of painted and oiled solid oak sticks or combination of oiled solid maple, nut and elm sticks.
