The Rhombus 13031 is a unique seat concept, simple and elegant with special detail in ergonomics and durability. This seat has been specially designed for venues with constant use such as auditoriums, parliaments, congress centres, corporate and VIP areas of stadiums and arenas.
Seat and backrest are composed of two blocks of moulded polyurethane foam that incorporate an inner metal structure, with flat springs and upholstery fully integrated into the foam by means of the Integral Form System.
The backrest padding is anatomically contoured, with lumbar support, and incorporates diamond patterns to give added comfort. The seat and backrest are upholstered and protected with a fully upholstered shell.
The seat tips up automatically by means of an extremely quiet double-spring system inserted inside the seat shell. It requires no lubrication of any kind.
The seat is mounted on two blow-moulded side panels with a housing system for the ball-and-socket joint, including a locking mechanism into which the seat pin fits. This enables easy seat replacement.
The side panels are fully upholstered and joined to a steel base, through which the seat is attached to the floor with hidden metal expansion bolts or other suitable type of anchorage for each type of surface.
The seat adapts to the specific slope of the floor at its base. Rows are formed by interconnected seats, ensuring rigid and stable row configuration, reinforcing the anchorage to the floor.
