The Tuoli Collection represents ISKU’s heritage, with the Tuoli 50 being a celebrated masterpiece that won a gold medal in the 1955 Design competition for its ergonomic quality. The collection, characterized by a graceful, nostalgic design from the 1950s, is widely adaptable to versatile interiors. Its core feature is stackability and durable construction, making it perfect for high-volume use in classrooms, offices, and dining areas.

Varieties include the Tuoli 50 and Tuoli 53 chairs, often available with height-adjustable cross-legs and wheels, making them suitable for dynamic learning and work environments. The chair frames are made of powder-coated steel or chrome, while the seat and backrest are available in laminate or veneer (oak, ash, or birch), with optional upholstery in ISKU standard fabrics or leathers. The availability of wheels ensures ease of movability, supporting quick changes in the functionality of any space.
