Jeff is a contemporary modular sofa system designed as a set of miniature architectures, skilfully combined to create multiple modular and reconfigurable scenarios. The distinguishing feature of Jeff is its harmony of volumes: the squared backrest pairs with a delicate seat to soften and give balance to the whole structure. A 90° corner unit featured by an oblique backrest, made from a highly comfortable and non-deformable polyurethane foam, resting on a plywood platform covered in fabric that is raised 3 cm off the ground by small feet. The backrest cushion further contributes to the sofa’s overall comfort, providing effective lumbar support. The lining is removable so that it can be cleaned and maintained with ease. A system of connecting hooks makes it possible to dismantle and reconfigure the sofa, customising it and adapting it according to the evolution of the space.
