Each assembly comprises a frame consisting of four feet and a double link bar to which the seats are attached. All the structural components are made of aluminium and there are no welds in the whole assembly, which prevents rusting and ensures easy maintenance. The quality and strength of the materials employed make it extremely durable and eliminate the need for maintenance. Seat and backrest are a single piece of 2 mm ergonomically curved sheet metal. These pieces are fixed in place at four points: two at the rear and two at the front. This ensures enormous strength and durability. Seat and backrest have two vinyl covered open-cell polyurethane foam cushions that provide the user with a higher standard of comfort while maintaining a high level of robustness, durability and safety. Both the polyurethane foam cushions are protected by a TS fire curtain and a vinyl covering, which makes them extremely hard-wearing and resistant to intensive daily use as well as easy to maintain and clean. Options include end and intermediary armrests and tables, which can be placed either between seat or at the end of the bench.
