Jean Batenburg for MI brutalist sideboard in ebonized oak, Belgium, 1960s

A brutalist four-door sideboard designed by Jean Batenburg for MI, Belgium, during the 1960s, executed in solid ebonized oak. The cabinet is made of solid oak and finished in a deep, dark stain, giving it a strong and architectural presence. Its most distinctive feature is the highly geometric treatment of the four doors, each composed of deeply faceted oak panels arranged in a repeating diamond pattern, creating a pronounced three-dimensional surface across the entire front. The angled facets interact strongly with the surrounding light, causing the appearance of the cabinet to change subtly depending on the viewing angle. Despite the expressive front, the overall form remains restrained and rectilinear, characteristic of Batenburg’s robust approach to cabinet furniture for MI. Opening the four doors reveals a contrasting lighter interior. The internal compartments are partially fitted with shelves and provide ample storage while retaining a straightforward and functional construction. The contrast between the dark exterior and the lighter interior further emphasizes the solid oak construction. The original keys are present. A distinctive example of Belgian furniture design from the 1960s, combining substantial solid-oak construction with an unusually graphic and deeply modelled facade. Good vintage condition with visible traces of age and use. The original dark stained finish shows rubbing, scratches, small marks and areas of wear, particularly along the top, edges and around the doors. In several places the wear reveals the warmer natural tone of the oak beneath. The original keys are present. Please refer to the detailed photographs for the overall condition.
