KUBE Solo – Compact Form, Endless Function

Comprising one premium sofa base and a single angled cushion, KUBE Solo is designed for stylish simplicity   and flexible living. Whether you use it as a statement armchair, a lounge seat, or an extra bed, KUBE Solo brings functionality to even the smallest of spaces.

Secured by two chrome-plated steel bars, KUBE Solo maintains both stability and rearrangeable flexibility. The

sofa base, made from high-density foam, strikes the perfect balance between firm support and lasting comfort

—whether you are sitting, lounging, or laying it flat for guests.


The angled cushion is filled with our EcoFoam Blend, encased in a non-woven inner sleeve that allows you to easily remove and wash the outer fabric cover without disturbing the cushion's structure.

Wrapped in plush corduroy fabric known for its tactile softness and superior durability, KUBE Solo is built to perform—and impress. Its modular design means you can change the colour anytime with a new cover set, or add accent pillows in contrasting tones for a more personal touch.
