The seat and backrest are each composed of a block of moulded polyurethane foam with an internal metal structure. The upholstery is joined to the foam using the Integral Form system, without seams or stitching. The Integral Form system guarantees accurate replacements if required.
A TS System fire barrier can be incorporated between the foam and the upholstery in both the seat and backrest, preventing fire from reaching the foam and delaying the spreading of flames and emission of toxic gases.
The backrest padding has an anatomical shape and incorporates vertical and horizontal grooves. The seat padding is anatomically shaped and smooth without any channels or grooves, in order to avoid dirt accumulation. The seat and backrest are protected by fully washable polypropylene shells that protect the rear of the upholstery.
The seat tips up automatically due to an extremely quiet double spring system inside the seat shell (tested to 500,000 cycles) that requires no lubrication of any kind.
Each chair is mounted on two metal pedestals incorporating a ball-and-socket joint system - including a locking mechanism - into which the seat pin fits. This enables easy seat replacement without having to dismantle the seat. The pedestals are made of steel tubing, and finished in black or grey epoxy paint. They are fixed to the floor by means of expansion plugs. The chair adapts to the specific slope of the floor at its base. Rows are formed by interconnected backrests and this provides totally rigid and stable rows, reinforcing the anchorage to the floor.
The armrests are made of semi-rigid polyurethane foam, with an inner metal structure. They incorporate a single, compact built-in cup holder. The end of row seats are upholstered. The seat has rear perforations which allow adequate acoustic absorption when the seat is tipped up and out of use.
The backrest can have a decorative rear upholstered section. The seat can be fully upholstered without losing acoustic properties.
The backrest can incorporate a headrest, with padding made in Integral Form and a protective shell. The backrest can also have an upholstered section at the top.
