KUBE Grand – Bold Comfort, Endless Flexibility
Crafted with precision, KUBE Grand features four premium sofa bases, two angled cushions, and two straight cushions—designed for easy rearrangement to suit your space and lifestyle. Built for both lounging and sleeping, this expansive modular configuration provides generous seating with the adaptability to transform as your needs change.
The sofa bases are made from high-density foam (T30) with a balanced elasticity of ILD 45, delivering the ideal blend of firm support and plush comfort. Whether you are stretching out for a movie night or accommodating overnight guests, KUBE Grand offers lasting comfort you can rely on.
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),
Wrapped in our signature luxurious corduroy fabric (90% polyester, 10% nylon), KUBE Grand combines durability with tactile elegance. With a Martindale rating of 35,000 and colour fastness to light of 4–5, the upholstery is made to withstand everyday use while retaining its look and feel. Chrome-plated steel bars provide essential stability while allowing for modular flexibility.
Personalization is at the heart of the KUBE Grand experience. Change the colour at any time by purchasing a new cover set—go bold, go neutral, or reinvent your space seasonally. Add extra cushions in contrasting tones for a unique, curated look that is all your own.
Part of the KUBE Collection, KUBE Grand is built for longevity. Instead of replacing your entire sofa as your needs evolve, simply reconfigure the layout or refresh the fabric. With KUBE Grand, design meets adaptability—delivering style, comfort, and practicality that lasts.
