The seat and backrest are composed of two blocks of moulded polyurethane foam that incorporate an internal metal structure. Upholstery is joined to the foam using the INTEGRAL FORM system, without seams or stitching. A 5-mm fire barrier (TS System) is incorporated between foam and upholstery on both the seat and the backrest to prevent fire from reaching the foam, delaying the spread of flames and emission of toxic gases.
Backrest padding is ergonomically contoured with lumbar support and headrest, and vertical and horizontal grooves are incorporated in the upper part of the backrest.
Seat padding has a smooth ergonomic form that is free of grooves of any type in order to avoid accumulation of dirt on the surface. The IF727 material used in finishings for the seat and backrest makes them fully washable and protects upholstery on their back parts.
The backrest reclines as per the users’ wish up to 15° using a pushbutton incorporated in the armrests. The backrest moves smoothly with barely effort. This mechanism allows the desired degree of inclination to be maintained without the need of continually exerting pressure on the backrest. Only when the seat is unoccupied it moves back to its original position by means of an immediate-return system. This system ensures that the hall always maintains an orderly appearance. The mechanism is completely silent and maintenance-free.
The seat base is fixed in an open position.
Both the seat and the backrest incorporate the TX acoustic system, consisting of acoustic perforations on the back and bottom covers. The system provides an excellent acoustic response. Optionally, the rear shell of the backrest can incorporate an upholstered panel. The seat bottom can be fully upholstered without losing any of its acoustic properties.
The Megaseat is mounted on a self-stable central pedestal and fixation to the floor is not required.
Seat arms are made of half-rigid polyurethane foam with an internal metal structure and incorporate a cupholder which is integrated within armrest on a single, compact piece.
The backrest can also be offered in the HR version. This type of back allows for the headrest to be integrated in the backrest rather than being added on as a separate element. The ergonomic advantage of this type of headrest is that it takes the form of a natural prolongation of the backrest, avoiding the need for an add-on accessory element.
