The Iren desk, designed by Kensaku Oshiro for Poltrona Frau, embodies the essence of Japanese calligraphy’s “iren” (意連), a concept that emphasizes the invisible yet deliberate continuity between points, lines, and characters, creating harmony even in separation. This desk reimagines modern workspaces by blending beauty, simplicity, and functionality, offering a fluid interaction between the user and the object. Its innovative design features two sliding surfaces that effortlessly expand to create additional work and storage areas, while a sleek metallic black box, elegantly wrapped in leather or saddle leather, discreetly houses USB and charging ports. The gently sloping upper surface ensures ergonomic comfort, providing optimal forearm support, and the wall-mounted version includes an optional LED light for use in low-light conditions. Available in both free-standing and wall-mounted versions, the Iren desk is crafted with precision, with the free-standing model supported by a solid ash sawnhorse base and the wall version by brackets. Customers can customize the sliding direction of the desktop to suit their preferences. Additionally, a downloadable 3D file of the Iren desk is available for those seeking to visualize or integrate it into their design plans.
