The Alu Bar Stool is designed by Muller Van Severen in collaboration with the architecture firm Bjarke Ingels Group (BIG). The stool originated from their joint design of the lounge bar at BIG’s headquarters. Its angular, geometric form reflects the distinctive design language of the Alu Chair, combining structural clarity with a bold use of colour.

Constructed from a lightweight uncoated aluminium frame, and finished with a UV-protected colour lacquer on the aluminium seat. The Alu Bar Stool is built to withstand outdoor conditions and retain its vibrancy and appearance over time. Featuring a flat seat and sturdy base structure, the stool provides support and stability. The integrated footrest offers comfort, making it ideal for extended use.

Available in three different heights, the stool is a versatile piece suitable for both indoor and outdoor settings. The lowest version can be used as a side table or low stool, while the 65 cm and 75 cm versions are perfect for counter and bar use. Muller Van Severen’s signature colour hues bring a playful yet sophisticated presence, enhancing the stool's sculptural appeal.
