Product Description

The Fixed Floor-Mounted Blue Upholstered Auditorium Chair with Retractable Wooden Writing Tablet, model AUD-WT-BL-001, is an unbranded fixed-row public seating solution designed for consistent, long-term use in high-traffic gathering spaces. Visually, the chair features a cohesive deep blue woven polyester upholstered seat, back, and side privacy panels, complemented by solid natural oak armrests finished with clear matte lacquer, brushed silver accent trim on the powder-coated aluminum support frame, and black embossed anti-slip steel kick plates at leg bases. When arranged in continuous rows via interlocking side brackets, the design creates a streamlined, formal layout suited to structured venue configurations.
Construction prioritizes durable, wear-resistant performance across all components. The 1.2mm thick stain-resistant blue upholstery is rated for 50000 Martindale abrasion cycles, built to withstand frequent public use. Seat and back cushioning uses cold-molded high-resilience polyurethane foam with a 45% rebound rate, supported by 15mm thick varnish-sealed multi-layer plywood internal shells; the finished seat cushion measures 90mm thick, with 70mm thick backrest padding and a 240mm high contoured lumbar support zone to encourage upright posture. The 4mm thick powder-coated aluminum frame anchors to floors via expansion bolts, with a galvanized steel spring and hydraulic damper seat return mechanism fitted with nylon bushings to eliminate squeaks and slamming, tested for 100000 return cycles. Each seat supports a 150kg static load, with a net unit weight of 28kg. The retractable solid wood writing tablet mounts to the right armrest via a silver metal pivot bracket, folding out 90 degrees to lock flat for use and retracting flush with the armrest when stored. Side panels include pre-drilled mounting points for seat and row number plates to simplify venue wayfinding.
This chair is suited for installation in lecture halls and university classrooms, where the integrated writing surface supports extended note-taking during presentations, as well as conference centers and formal meeting rooms where its quiet operation and polished appearance align with professional event standards. Its robust construction also makes it appropriate for government and institutional assembly halls with high daily public foot traffic, corporate training rooms where tip-up seats and retractable tablets enable flexible space reconfiguration between sessions, and auxiliary seating areas in theaters and performing arts venues where contoured back support accommodates long event durations. For procurement, note that each unit ships in two cartons, with a 40-minute per-set assembly time, and 135 sets can be loaded in a 20GP container at 85% space utilization. Seats are compatible with flat or tiered venue floors, and connect seamlessly to form stable, continuous rows without additional structural supports.
