Poliform Westside sofa system

Westside is a modular system: upholstered modules that stand side by side in whatever configuration a room needs, with three coffee tables drawn to go with them. In 2023 Jean-Marie Massaud added Westside Soft, the same system with feather padding.

One system, two levels of softness

The modules are the product. Placed in a row they make a long sofa; turned, they make a corner; separated, they make two seats and an island. That flexibility is what people buy a system for, and it is also where quotes go wrong, because a module list assembled by eye on a showroom floor rarely matches the room at home. We work from the room.

Westside Soft, from 2023, is the important variant. Feather padding behaves differently from foam: it gives more, it takes the shape of whoever last sat in it, and it needs plumping. Some people find that luxurious and some find it untidy, and the difference is worth knowing before ordering, not after.

The standard version keeps a firmer line and stays neat without attention, which in a living room used by a family is usually the more practical answer. Both versions use the same modules, so the choice is about filling, not about layout.

Three coffee tables complete the system, in different materials and shapes, drawn to sit inside a module arrangement rather than in front of it. In an open plan room that is what stops a long sofa from turning into a barrier.

Feather gives and needs plumping. Foam keeps its line. Same modules, different life.

Massaud reworked his own system four years later rather than replacing it, and only the filling changed.
