The Red Upholstered Fixed Floor-Mounted Auditorium Chair with Wood Armrests, model AUD-RED-WDARM-580, is purpose-built as ganged fixed public seating for high-traffic indoor venues. Its coordinated red upholstery covers the seat, high backrest, and multi-layer plywood side panels, paired with warm, varnished solid wood armrest tops finished to resist scratches, creating a polished, uniform appearance across connected rows. The structure is anchored by a powder-coated cold-rolled steel stanchion frame with 1.8mm wall thickness, supported by 2.5mm thick steel base plates with pre-drilled anchor holes, with perforated ventilation grilles integrated at the stanchion base. The seat and back use cold-cured high-resilience polyurethane foam at 65 kg/m³ density, with 140mm thick cushioning at the seat center and 120mm thick padding at the back’s lumbar support zone, set to a 105-degree fixed recline for long-session comfort. A double-spring silent gravity mechanism lifts and returns the seat automatically when unoccupied, while fixed rigid armrests sit at 640mm from the finished floor, providing stable arm support and a mounting point for optional add-ons. Integrated left-side brackets accommodate cup holders, ticket pockets, or writing tablets as needed, and S-shaped spring suspension in the inner seat frame supports consistent weight distribution. Each unit supports a 260 kg static user weight, with 250 kg vertical static load capacity per armrest. This chair is suited for permanent row installation in school and corporate lecture halls, commercial cinemas, performing arts theaters, large conference centers, government assembly halls, courtrooms, and public ceremony venues, and works with concrete raised access or finished solid floors. Layout planning requires 1070mm minimum row spacing for accessible egress and sufficient legroom. For procurement, note the product ships as one set across two cartons, with 40 minutes of assembly time per set, and plan for permanent anchoring via expansion bolts during installation, selecting upholstery between woven commercial stain-resistant fabric or stain-treated PU leather, and choosing beech or oak for the solid wood armrest tops to match venue design requirements.
