The Dual Seating System, with its reversible seat and backrest design, enables versatile use in various orientations, ideal for adaptable spaces like auditoriums, museum halls or waiting areas. The Dual seating system is a mechanical system that controls the movement of both the seat and the backrest, allowing a double use of them, depending on the orientation or the use of the room. This system can be fixed to the floor and is adaptable to several seat models, allowing a smart use of the space, being a perfect option for waiting areas and rooms or auditoriums that can be divided for different uses at the same time. The seat automatically folds-up when it is vacated, using a silent and soft mechanism that has been developed with a no finger trapping system to ensure maximum security. When folded, both pieces store in its vertical position, optimizing the use of the space. It becomes the perfect solution for multipurpose rooms when it is combined with Figueras’ movable seating systems Mutarail or Mutasub, providing many different configuration options depending on the needs of each event.
