A modular seat made up of fully replaceable parts that has very generous dimensions. The nominal minimum distance between axes is 58 cm. This distance has not been achieved by adding wider armrests or supplementary items between the seats, but by increasing the dimensions of the seat and backrest, so that the actual minimum space for the user is 56 cm, a measurement that provides a high degree of comfort. The seat and backrest consist of two moulded polyurethane blocks about an internal metal structure and upholstery, without any seams or stitching, that is fully integrated with the foam by means of the INTEGRAL FORM system. Between the upholstery and the foam of both the seat and the back, there is a 5 mm-thick TS System fire curtain that prevents fire from reaching the foam, thus slowing down the emission of toxic gases and flames. The backrest cushion has a specially designed anatomical shape with lumbar support and headrest and vertical and horizontal fluting in the headrest. The seat cushion is also anatomically shaped, but is completely plain, without any channels or fluting, to keep out the dust. The seat and backrest are finished in fully washable IF727 material that protects the upholstery at the back. The seat tips up automatically thanks to an extremely quiet double spring system inside the seat shell (tested to 500,000 cycles) that requires no lubrication of any kind. The chair is mounted on a central foot attached to an internal connecting bridge that links the seats together and allows the formation of completely rigid and stable rows. The feet have a tubular steel structure finished in black or grey epoxy paint and are fixed to the floor by means of expansion plugs. The seat can be adapted to any particular slope by regulating the base of the foot. The armrests are made of polyurethane foam on an inner metal structure. Rows are formed by joining the backs of the seats together. This provides a totally rigid, stable structure that reinforces the floor anchorage. The arms are made of polyurethane foam with an inner metal structure and incorporate an integrated cupholder in a single, compact piece. Both the seat and backrest incorporate the TX acoustic system, a set of holes at the rear, which give an excellent acoustic response. Optionally, the upper part of the rear panel can of the backrest may also be upholstered. The seat can be fully upholstered without losing any of its acoustic properties. The backrest can also be made with HR. This type of backrest features a headrest that is integrated into the backrest. In other words, it is not an add-on, but is actually an integral part of the backrest. This headrest system has a clear ergonomic advantage, as it is a natural extension of the backrest, not a separate item that is added onto it.
