We design, manufacture and install retractable grandstands and seating systems that optimise the use of space. Whether for a new development or the renewal of an existing venue, every solution is engineered to meet current standards while making the best possible use of the available space within the architectural, technical and regulatory constraints of each project.
Working closely with architects, municipalities, consultants, contractors, venue operators and end users, we develop tailor-made solutions that balance functionality, safety, comfort, operational efficiency and architectural quality.
Founded in 2008, COS combines innovative technologies such as rigid chain drive systems and intelligent automation with durable engineering. All COS grandstands are designed, engineered, manufactured and assembled at our EN 1090-certified production facility in Belgium, giving us full control from concept to installation and after-sales support.
Our solutions are designed for long-term performance, adaptability and sustainable use of space.
COS has contributed to projects across Europe, including Nokia Arena (Tampere, Finland), Futuroscope (Poitiers, France), Kursaal (Dunkerque, France) and Sportcampus Zuiderpark (The Hague, The Netherlands).
COS TI26/32 and TI42/50 combine the proven principle of a telescopic grandstand with the flexibility of a fully mobile unit.
With standardised dimensions and availability from stock, they provide a practical solution when additional spectator capacity is needed at short notice.
Each unit can be moved manually and positioned wherever required. Integrated fold-out floor protection plates distribute the load during movement, protecting delicate sports floors.
Once positioned, the grandstand telescopes out to provide comfortable tiered seating with clear sightlines. When closed, its compact dimensions minimise the space required for storage.
COS retractable grandstands are custom engineered for sports halls, arenas and multifunctional venues.
The platforms are driven by rigid chain technology powered by a central gearmotor, ensuring controlled and synchronised opening and closing. The system operates independently of floor friction, providing excellent stability without requiring additional downward pressure to generate traction.
Each grandstand is designed in accordance with EN 13200 and manufactured at our EN 1090-certified production facility in Belgium.
Capacity, seating configuration, dimensions and level of automation are tailored to the specific project, creating a durable and reliable solution for intensive use.
COS movable telescopic grandstands combine the flexibility of a custom-engineered retractable grandstand with the ability to reposition the complete unit within a venue. Designed for larger capacities and dimensions, each grandstand is tailored to the building, seating requirements and operational needs. Depending on the floor and application, movement can be achieved using an air-cushion system with compressor or a custom transport system. Rigid chain technology provides controlled, synchronised opening and closing, independent of floor friction. Designed according to EN 13200 and manufactured at our EN 1090-certified production facility in Belgium.
