Atoll by B&B Italia is part of a modular sofa system and it is the refined expression of a balanced aesthetic shape and a decisive contemporary style, but at the same time it is expression of extreme elegance. The starting point that allows you to compose different Atoll compositions are three base platforms that are completed with armrest and backrest to form different types: cockpit sofas, dormeuse, corner terminals, single or modular elements with chaise longue and pouf elements. A further characteristic element of Atoll is a roller cushion that is available in two sizes and bound to the die-cast structure by means of leather straps. The roller is an accessory to be freely inserted between the seat cushion and the base structure to become an armrest or backrest element.
