Product Description

The unbranded AUD-BW-590BL fixed floor-mounted auditorium chair is purpose-built for high-traffic public assembly settings, balancing polished visual appeal, durable construction, and user-centric functionality. Its design pairs soft commercial blue woven polyester upholstery with warm light oak finished bentwood panels, anchored by a sleek black powder-coated single steel pedestal for a streamlined, formal look suited to professional and institutional spaces. The closed-loop bentwood armrests integrate a subtle open recess for small personal items, while clean, consistent stitching with heavy-duty polyester bonded thread lends a refined, uniform finish across fixed seating rows. Construction prioritizes long-term heavy use: seat and back cushions are shaped from cold-molded high-resilience PU foam, with the seat cushion at 60 kg/m³ density and 140mm thickness, and the back cushion at 55 kg/m³ density and 135mm thickness, wrapped in abrasion-resistant fabric available with optional flame-retardant or antistatic treatments. Armrest and side panels use 18mm thick 7-layer bent hardwood sealed with baked clear lacquer, while the seat underside features 13mm thick perforated bent plywood with uniform acoustic vents. The central 2.2mm thick cold-rolled steel pedestal connects to a 4mm thick pre-drilled round floor plate for rigid concrete anchoring, and the zinc-plated steel tip-up hinge uses a double torsion spring and hydraulic damper rated for 100,000 operation cycles. Each chair supports a 260 kg static load, with an assembled net weight of 35 kg. Key practical features support smooth venue operation: the gravity-activated tip-up seat lifts automatically when unoccupied, folding to a narrow depth to keep aisles clear, while the integrated hydraulic damper slows return to eliminate disruptive impact noise during events. The 10-degree fixed back recline delivers ergonomic support for extended seating, and the perforated seat underside provides sound absorption to reduce echo in large spaces. The chair is compatible with optional add-ons including row number plates, cup holders, and fold-out writing tablets. It is well suited for university lecture halls, cinemas and performance theaters, corporate conference halls, government auditoriums, and K-12 school multi-purpose spaces, with a recommended minimum 1100mm spacing between straight or curved rows for accessible egress. For procurement, note each unit ships in two cartons, requires 40 minutes of assembly per seat, and supports 135 set loading in a 20GP container at 85% space utilization. Specify required fabric treatments and accessory add-ons at the time of order to align with venue safety and functional needs.
