RHOMBUS CORPORATE ARMCHAIR 13031-55 | COMMERCIAL ARMCHAIRS
The Rhombus 13031 is a unique, simple and elegant chair concept with special details in ergonomics and durability. This seat has been specially designed for venues with constant use such as auditoriums, parliaments, conference centres, corporate and VIP areas of stadiums and arenas.
The seat and backrest are made up of two blocks of molded polyurethane foam that incorporate an internal metal structure, with flat springs and the upholstery fully integrated into the foam through the Integral Form System.
The backrest padding is anatomically contoured, with lumbar support and incorporates a diamond-shaped design for added comfort. The seat and backrest are upholstered and protected with a fully upholstered shell.
The seat tilts automatically by means of an extremely quiet double spring system, inserted inside the seat shell. Does not require lubrication of any kind.
The seat is mounted on two blow-molded side panels with a ball joint housing system, which includes a locking mechanism into which the seat axle fits, allowing for easy seat replacement.
The side panels are fully upholstered and attached to a steel base, through which the seat is fixed to the floor with hidden metal expansion bolts.
The seat adapts at the base to the specific slope of the ground. The rows are made up of interconnected seats, which ensures a rigid and stable row configuration, reinforcing anchorage to the ground.
