The KUBE Duo – The Future of Sofas
Comprising two high-density foam sofa bases and two angled cushions, The KUBE Duo is engineered for effortless flexibility and modular living. Secured by three chrome-plated steel bars, it retains structural stability while allowing you to rearrange or expand with ease. Whether you are sitting or sleeping, the RX33-grade high-density foam offers the perfect balance of firm support and plush comfort.
The angled cushions are filled with our signature EcoFoam Blend, encased in a non-woven inner sleeve. This design allows the outer fabric to be easily removed for cleaning or cover changes without disturbing the internal structure. Wrapped in a luxurious corduroy fabric (90% polyester, 10% nylon), The KUBE Duo is as durable as it is stylish—crafted to stand the test of time in both form and function.
Customization is at the heart of The KUBE Duo. Choose from a variety of cover colours to reflect your style, or refresh your space with a new look as your tastes evolve. Want to expand? Transform The KUBE Duo into our larger KUBE Corner sofa— perfect for growing families, entertaining, or creating a cozy play area.
Whether you are moving into your first apartment or redesigning your dream home, The KUBE Duo grows with you. It is not just a sofa; it is a modular lifestyle solution built for comfort, adaptability, and life’s ever-changing rhythms.
