The backrest lowers and at the same time moves into a vertical position, reducing overall dimensions. Seat and backrest fitted with variable layout transfer mechanism to guarantee maximum comfort for the user, who can sit in a more upright or relaxing position. Backrest available in two heights with plywood internal structure, padding in flame-retardant, non-deformable expanded polyurethane. CertiPUR® certified padding. Wooden components with low formaldehyde emission. Armchair equipped with a gravity system which releases and tips up the seat with “soft-close” movement slowed by a damper. At the same time the seat drops and uprights, reducing the volume of the armchair and increasing the available space between rows with a considerable advantage for the audience access/exit and for the cleaning and maintenance operations.
