The sofa by Cubit® When design is versatile but never arbitrary, then it’s Cubit®. The modular sofa system by Cubit® is convincing in any dimension, for any use and style. And this is the reason: the minimalist language of form develops out of the technical construction. The slot-in system is essential to each element apart from the ottoman. An L-shaped bentwood connects the seat and the backrest and side elements. The five basic types can be configured to over 300 models.
