Product Description

The 3-Seat Fixed Ganged Auditorium Chair with Retractable Writing Tablet and Wood Armrests, model AUD-3S-WT-001, is a purpose-built public seating solution designed for high-traffic shared venues. Delivered as unbranded, flat-packed units requiring 40 minutes of assembly per 3-seat set, each unit ships across two cartons, with logistics optimized for bulk transport to support large-scale venue fit-outs.
Visually, the seating presents a cohesive, professional profile: dark upholstered high-back seats and backs are paired with warm finished wood armrest tops, anchored by a slim, matte powder-coated metal frame that creates clean, unbroken sightlines when arranged in rows. When seats are tipped up for storage between uses, the unit maintains a narrow footprint that keeps aisles and circulation paths clear.
Construction centers on durable, high-use rated materials. The seat and backrest feature thick cold-cured high-resilience polyurethane foam, supported by shaped multi-layer plywood internal panels to deliver ergonomic contouring, wrapped in dark, abrasion-resistant, flame-retardant fabric or PU leather. Armrest tops are finished solid oak or wood veneer with multi-layer clear coating, paired with side panels matched to the upholstery tone. The support frame and floor legs are formed from thick cold-rolled steel, treated for corrosion and scratch resistance before powder coating, with galvanized steel expansion bolts for secure floor anchoring. The integrated retractable writing tablet uses a die-cast aluminum alloy bracket with silent pivot and anti-panic release, supporting a wear-resistant melamine-finished plywood surface with an integrated pen slot.
Functional design prioritizes usability and low disruption: gravity counterweight auto-return tip-up seats operate with silent soft-close action when unoccupied, with nylon bushings and buffers keeping operational noise below 30dB. The writing tablet swings 180 degrees to stow flush inside the armrest when unused, with a fixed 6.5-degree tilt to support comfortable writing. A shared horizontal steel underframe gangs seats into rigid continuous rows, suitable for both straight and curved layouts, with each seat rated for 160kg of static load, and armrests rated for 250kg of vertical static load.
This seating is well suited for college lecture halls, where the integrated tablet supports consistent note-taking and the stepped-floor compatible fixed mount aligns with tiered room design; theaters and performance venues, where the contoured high back supports extended seated comfort for audiences; corporate conference centers, where quiet operation and polished finish suit formal events; government and institutional auditoriums, where the anchored fixed design and flame-retardant materials align with public venue requirements; and church or multi-purpose halls, where flexible ganging supports custom row arrangements. When planning procurement, note that companion accessories including row number plates, aisle LED lights, cup holders, and under-seat USB power outlets are available to customize installations to specific venue needs, and bulk orders can leverage optimized container loading for cost-effective delivery.
