Rhombus 13037-55

The Rhombus 13037 is a new concept of integral seat with elegant and sober design. With special care in ergonomics and durability, the Rhombus 13037 has been specially designed for venues with constant use such as auditoriums, parliaments, congress centres, corporate and VIP areas of stadiums and arenas.

Seat of generous dimensions, ergonomic, of great resistance and durability, composed of totally interchangeable elements

The seat and backrest are composed of two blocks of moulded polyurethane foam and incorporate a metal interior structure, flat springs and upholstery fully integrated into the foam by means of the Integral Form system without seams or stitching Both are protected by a polypropylene casing that protects the back of the upholstery

The backrest mattress is anatomically shaped, with a fanny pack, incorporating rhombuses in the body of the same that increase comfort

The seat cushion is anatomically shaped and smooth, without any type of channel or groove to avoid the incorporation of dirt

The seat is automatically folded by means of a double spring system inserted inside the seat, without any type of lubrication and extremely silent

The seat is installed on two side panels made of polypropylene by means of a blowing technique that gives them great rigidity and lightness They have an integrated housing system for the ball and socket joint, with a locking mechanism, which receives the axis of the seat and allows easy replacement of the seat without disassembling the seat

Both the end of the row and the intermediate panels are fully upholstered The arms are made of polyurethane foam with an internal metal structure

The sides end in a lower steel base, by means of which the seat is fixed to the floor with hidden anchors The seat adapts to the specific slope of the room at the base of the foot

The rows are formed by interconnected seats and allow the formation of totally rigid and stable rows, reinforcing the fixation to the floor

The seat has holes in the back that allow adequate sound absorption when the seat is raised and unused
