The KUBE Trio – Where Comfort Meets Customization

Crafted with precision, The KUBE Trio features three premium sofa bases and a combination of two angled cushions and one straight cushion. Designed for both lounging and sleeping, this modular piece provides a perfect balance of firm support and soft comfort. The sofa bases are made from high-density foam (RX33) with an elasticity rating of 45, offering long-lasting performance and ergonomic comfort.

The cushions are filled with our signature EcoFoam Blend, encased in a non-woven inner sleeve that allows the outer fabric to be removed and cleaned without disturbing the structure inside.

Upholstered in a durable corduroy fabric (90% polyester, 10% nylon), The KUBE Trio brings a warm, textured aesthetic to your living space. Chrome-plated steel bars provide structural support while maintaining the flexibility needed for rearrangement and expansion.

As with all pieces in the KUBE family, customization is easy. Swap out cover sets to change colours or textures, add bold pillows for contrast, or expand into a larger layout with compatible KUBE modules. Built for evolving spaces and lifestyles, The KUBE Trio blends practical design with timeless comfort.
