304.cage is a Rotterdam studio by Bram Schlangen shaping furniture and objects with an industrial calm—stainless steel, aluminium, graphic lines. Founded in 2023, the practice keeps forms spare and surfaces honest so pieces settle into a room and earn their keep. Beyond the studio line, 304.cage takes on set design and creative direction for art and fashion projects. Recent showings span Milan Design Week and Collectible Brussels, with works available via select galleries and retailers. Minimal, sculptural, built to last—quiet tension for real interiors.
