Claesson Koivisto Rune sideboard

The Sierra sideboard, designed by Claesson Koivisto Rune in 2010, is a sophisticated expression of contemporary Scandinavian design, where architectural geometry and natural materiality converge into a highly sculptural and functional form. Created by one of Sweden’s most internationally acclaimed design studios, the piece reflects Claesson Koivisto Rune’s signature approach—merging minimalism with expressive surfaces and refined craftsmanship.

At the heart of the design is the striking facade, composed of precisely articulated geometric panels. These angled, faceted planes produce a dynamic interplay of light and shadow, giving the piece an ever-changing surface quality that shifts with the ambient light. The faceting is subtle yet sculptural, transforming the sideboard into a tactile and visually engaging object that blurs the line between furniture and art installation.

The body of the sideboard is expertly veneered in whitewashed oak, offering a soft, natural palette that complements the architectural complexity of the front. The whitewash highlights the oak’s grain pattern while maintaining a light, matte surface that enhances the overall sense of visual calm and Nordic sensibility. This finish balances the expressive front with a refined, understated material tone, allowing the intricate design to take center stage without appearing heavy or ornamental.

Supporting the veneered cabinet is a sleek, brushed metal base—minimal in profile yet robust in structure. The metal finish adds a subtle industrial counterpoint to the organic quality of the wood, reinforcing the piece’s contemporary aesthetic and contributing to its floating appearance.

The Sierra sideboard is not only a statement piece in terms of visual design but also offers substantial storage behind its sculptural facade. The interior is typically configured with adjustable shelves, maintaining the studio’s commitment to functionality and usability without compromising on form.

Claesson Koivisto Rune—founded by Mårten Claesson, Eero Koivisto, and Ola Rune—has become one of Scandinavia’s leading design firms, known for their holistic approach across architecture, interiors, and product design. Their work often explores geometric abstraction, material integrity, and minimal ornamentation, with the Sierra sideboard standing as a clear manifestation of these values.

This example is in excellent condition, showing minimal signs of wear consistent with gentle use. The oak veneer retains its even tone and texture, and the base remains structurally and visually intact.

The Sierra sideboard is both a functional storage solution and a sculptural focal point, making it suitable for modern interiors that prioritize form, innovation, and craftsmanship. As a collector’s item and a testament to contemporary Nordic design thinking, it exemplifies Claesson Koivisto Rune’s continuing influence on the evolution of Scandinavian aesthetics.
